Recycling

Environmental impact is a value judgment no different from weighing factors like price, performance, after-the-sale service, personal tastes or social concerns when making a purchase. Some of those judgments, like which items are over-packaged, can be made in the aisle as you scan the shelves. Others involve reading labels, and if your heart is really in this, you can do some homework to arm yourself with information before you hit the store. In addition to labeling about whether a product or package is recyclable, you may also see:

• Other single-attribute labeling, such as biodegradable or not tested on animals
• Advertisement of a corporation’s financial support of a particular environmental or social organization or cause
• Promotion of a corporation’s environmental, personnel or social policies
• Third-party certification, seals of approval or recommendations

You may want to scrutinize any such claims. See if independent observers can back a corporation’s positive self-assessment. The Federal Trade Commission, as well as several consumer information and environmental organizations, can be good resources. The commission has taken action in a number of cases involving alleged deceptive or unsubstantiated environmental advertising claims.

Some third-party consumer and environmental groups (Green Seal is the most prominent in the United States) look at the life cycle analysis of the environmental impact of a product from extraction of the raw materials, through production and use to final disposal or recycling. The impact of recycling is factored into such analysis but sometimes takes a back seat to other environmental concerns. A household cleaner in a 100 percent post-consumer paperboard box may rank lower than one with less post-consumer fiber because the product is high in acidity or contains volatile organic compounds.

Recycling is just part of the picture. Reducing the amount of waste you generate and reducing your reliance on disposable convenience products are other facets of waste reduction. Waste reduction saves money, conserves natural resources and reduces pollution, including the gases that cause climate change.

Here are some easy things you can do right now to reduce your waste and, in many cases, save money:

• Buy less/use more. Americans throw away more than 1/3 of the food they buy in grocery stores.
• Buy reusable containers with lids or reuse margarine and deli tubs to store leftovers instead of using wraps, bags and foil.
• Buy in bulk.
• Buy quality.
• Buy concentrates.
• Bring your own bags. Many stores sell canvas shopping bags and give small discounts to shoppers each time they use them. Don't accept a bag at checkout if you're buying a few items you can handle without the extra waste.

Zero Waste

You may have heard the term zero waste, but what does it mean? Zero waste takes reduce, reuse, recycle to a whole new level. Recognizing that the steps we've already taken may not be enough to ensure a sustainable future, the zero waste initiative focuses on finding new uses for materials that used to be considered waste. Manufacturing, packaging, standard use and even marketing practices are examined to see what steps can be taken to improve efficiency, save money, reduce water use, prevent creation of pollution and emissions, conserve energy and minimize or halt the use of virgin materials.

Public, private, governmental organizations and businesses are beginning to examine and embrace zero waste policies as a way to protect health, save money, reduce climate change and promote sustainability. Even you can work toward a zero waste future. Here are three new words to get you on the right track: Eliminate; Minimize; and Substitute. 

One Family's Story

'Trash Day' usually entails lifting over-filled plastic bags to the curb or rolling 90-gallon totes down the driveway, but not for the Johnson Family in Mill Valley, California. They choose to live a "zero waste" lifestyle and reap the rewards. Below are some tips they offer to lower your waste in the kitchen.

Thanks in large part to citizen demand, recycled material is turning up in an increasing array of products and packaging. By seeking out and selecting those products, you can encourage manufacturers to use recycled material in their feedstock and motivate them to use even more recycled material.

A high percentage of post-consumer materials can be found in four types of product packaging:

• Aluminum beverage cans: The average aluminum beverage can is made of more than 51 percent recycled aluminum from old beverage cans. With more than five of every 10 aluminum cans being recycled in the United States, they are the most recycled beverage container.
• Glass bottles and jars: Approximately 35 percent of glass in glass bottles in the United States is recycled material. Generally, glass must be separated by color to have value in new bottle manufacture, but mixed glass is also used as abrasives in sandblasting, aggregate in roadbed construction, beads in reflective paint, frictionators in matches and ammunition and other applications.
• Steel cans: A little less than 60 percent of steel cans sold in this country are returned for recycling into a variety of products. More than 28 percent of the steel in an average steel can is post-consumer.
• Molded pulp containers: Paperboard egg cartons, fruit trays and flower pots are made from high percentages of recycled paper. Overall, recycled paper supplies about 35 percent of the U.S. paper industries’ raw materials.

Support the Recycled Materials Market

Recycled material is used to produce several other types of packaging and non-durable goods, but they compete with items made with no post-consumer material that often are priced lower than recycled-content counterparts. Seeking and purchasing recycled content items can be particularly important as it sends a strong signal to manufacturers that recycling is good for business.

• Paperboard boxes: Recovered paper and paperboard accounted for nearly 38 percent of new paper production in the United States in 1998 but read the label for post-consumer content.
• Plastic bottles and jugs: Of the two types of plastic beverage containers generally accepted by residential recycling programs, HDPE is generally used to make plastic lumber and containers for non-food items. PET goes primarily into textiles and carpeting. Soft drink and bottled water makers have been slow to use recycled PET in new bottles, but new technology (developed with the support of a Recycling Market Development Grant) is making this sort of “closed loop” recycling more feasible. America’s plastics manufacturers have far more capacity to use recycled plastic than consumers are recycling. Plastics increasing role in consumer packaging make it particularly important to recycle plastic and to seek products made from post-consumer plastic.
• Bath and facial tissue, napkins and paper towels: Competitive in performance and price with non-recycled alternatives, these disposable paper products are often made from lower grades of mixed paper. While not recycled into new paper products for obvious reasons, paper products that are flushed after use are often composted with other wastewater sludge. Other paper tissues and towels can be added to the kitchen scrap compost pile.
• Writing paper and envelopes: The push by some business and government agencies to provide markets for high-grade recycled office paper helped make high-grade recycled papers more widely available.

Make Informed Buying Choices

Some manufacturers, advertisers and marketers know people are shopping with the environment in mind, and some use labeling to create the appearance that their products are compatible with those values. Just because a product or package carries a recycling symbol does not mean it is recyclable or that it is recycled in your community.

The Federal Trade Commission (FTC) has issued Green Guides designed to help marketers ensure that the claims they make about the environmental attributes of their products are truthful and non-deceptive. To help users understand these guides, the FTC has developed a special website that answers some of the more common questions about green marketing and the standards businesses must meet. Questions or complaints about suspicious marketing claims can be made with the FTC Consumer Response Center at (202) 326-2222. The Internet and the local library are good places to launch your own search for the facts. Here are a few things you should know:

• A product or package may be marketed as recyclable if it can be separated and collected from household and commercial trash for reuse or recycling through an established recycling program. It does not necessarily mean the item is recycled in your community's recycling program. If you're not sure, contact your recycling service provider to find out.
• As a customer service, some businesses recycle products that aren’t part of the community recycling program. For example, some grocery stores take back their plastic grocery bags. Some toner cartridge makers allow consumers to return their empty cartridges for re-manufacturing.
• Many disposable cameras are actually recycled after the film is processed.
• Recycled may refer only to scrap material gathered during manufacturing, such as scraps of paper left over from cutting envelopes. Products and packages made from material gathered in community recycling programs should be identified as post-consumer material and should indicate what percentage of the material is post-consumer.
• If a label says recycled, it must tell the percentage of recycled content, unless it’s 100 percent.
• The international recycling symbol means that the product is both recyclable and made of recycled materials. If only one of these claims is true, the manufacturer should say which one.

Never recycle or dispose of aerosol cans or propane gas cylinders unless they are empty. 

Many household recycling opportunities accept empty aerosol cans. If the product is non-toxic, the remaining aerosol can contents can be discharged into a box (or onto trash) outside and away from ignition sources, children and pets. Protect your eyes and skin and avoid breathing vapors. Allow the box to dry outside, and dispose of the dry box and empty can in your regular trash or recycle. Caution: Do not dispose of the wet box into a closed garbage can because vapors can build up inside the can and could cause a hazard.

Propane gas containers can be recycled as metal scrap or disposed of only after the valve is removed by a professional and there is a hole that clearly shows it is empty. If you are considering refilling the cylinder, be sure to take it to a knowledgeable gas cylinder retailer or recycler.

Most appliances can be easily recycled at a scrap yard. Refrigerators, air-conditioners and humidifiers contain environmentally harmful refrigerants that should be removed before recycling. If the scrap yard is not certified to remove refrigerants, then you should have the appliance tagged by a certified refrigerator service company after the refrigerant is removed.

Contact your solid waste management district or check the Ohio EPA recycling directory to see if there is a recycling opportunity near you. You can also refer to U.S. EPA’s information about safe disposal of refrigerated household appliances.

Auto service centers and auto parts stores may accept some automotive fluids, including antifreeze, used oil, transmission fluid and power steering fluids from residents. Automotive fluids such as gasoline and brake fluid are dangerous because they are flammable or reactive. Contact your solid waste management district or one of these registered used oil collection centers to see if there is a recycling opportunity near you.

Check the Ohio EPA recycling directory to find locations that accept batteries from residents. Batteries Plus stores will also accept most battery types from residents for free.

Retailers of lead acid batteries (car batteries) are required to take your old battery for recycling when you buy a new one, and many computer and retail stores will often accept rechargeable batteries for recycling. 

Many electronic items are recyclable. Best Buy, Staples and other retailers offer free recycling for most electronic products.

Check the Ohio EPA recycling directory or contact your solid waste management district to see if there is a recycling opportunity near you. U.S. EPA’s Plug Into eCycling website is a great source of information about handling and disposing of used electronics safely. Their site also includes statistics and a link to the Electronics Waste Management in the United States through 2009 report.

For information about proper handling and disposal of fluorescent bulbs, including guidelines for cleaning up a broken bulb, see Ohio EPA’s compact fluorescent light bulb webpage. 

Fluorescent bulbs contain small amounts of mercury and recycling is recommended. Mercury is also found in other household items, such as old thermometers and thermostats. Home Depot and Lowe's offer free recycling of compact fluorescent bulbs at all of its store locations. Contact your solid waste management district or refer to this list of computer, fluorescent lamp and ballast recyclers to see if there is a recycling opportunity near you.

Household hazardous waste includes cleaning products, solvents/paint removers, stains/varnishes, unknown substances, as well as aerosols/propane tanks, automotive fluids/used oil/other fuels, batteries, electronics, fluorescent bulbs/thermostats/thermometers, paint and pesticides/fertilizers. Some household hazardous waste can injure sanitation workers, contaminate septic tanks or wastewater treatment systems if poured down drains or toilets and present hazards to children and pets if left around the house.

Latex paint can be dried out and put in the trash. You can purchase paint hardeners from paint and home improvement stores, or you can mix the paint with cat litter or sawdust. Leave the lid off to speed up the drying process and to allow your trash hauler to verify that the paint is not liquid. Do not leave open cans near ignition sources, pets or children.

Check the Ohio EPA recycling directory or your solid waste management district to see if there is a recycling opportunity near you.

Pesticides are chemicals used to kill or control household and garden pests such as weeds, insects and rodents. Most pesticides are designed to work on a wide number of pests. This also makes the pesticides harmful to useful insects, animals and plants. Improper pesticide disposal can harm humans, pets, livestock and the environment. Throwing pesticides in the trash, on the ground or pouring them down the drain can pollute lakes, streams and drinking water.

When you consider using pesticides, first ask yourself these questions:

• Do I really need a pesticide to get the job done?
• What is the least toxic product that I can use?
• How much do I need to buy?

To avoid possible health and environmental problems, carefully follow the instructions on the household pesticide container and use only as much as the manufacturer recommends to get the job done. If you must use a pesticide, it’s important that you use, store and dispose of it properly.

Disposing of loose needles, lancets and syringes (sharps) into household trash poses a risk to family members and solid waste workers who must handle the waste. Ohio law allows for the disposal of sharps generated by an individual for the purposes of their own care or treatment at home. However, it is strongly encouraged that all sharps be packaged in an appropriate container and labeled to convey its potential hazard.
Ohio EPA's Disposal of Household Generated Sharps guidance document provides disposal tips to homeowners who generate sharps for purposes of their own care or treatment.

Illegally dumping scrap tires creates a nuisance that obstructs the natural beauty of Ohio’s landscape and can accumulate water, creating a breeding ground for mosquitoes that transmit a variety of diseases to people and animals. Illegally open burning scrap tires can create immediate health hazards to persons with breathing problems.

These lists of scrap tire facilities and scrap tire transporters are available to see if there are local companies that will accept your tires. Most tire dealers and some Ohio EPA licensed solid waste facilities will also accept tires for a fee.

Yard waste and kitchen food scraps make up 25 percent of the U.S. municipal solid waste stream. Backyard composting is a great way to recycle this waste. Many homeowners find backyard composting easier than bagging their yard-waste, storing it and hauling it to the curb or drop-off center. This Citizen’s Guide to Composting has more information.

Your household’s trash service may provide yard waste collection. U.S. EPA’s website also has information on composting and a guide to creating your own compost pile. Contact your solid waste management district or refer to this list of Ohio EPA registered composting facilities to see if there is a composting facility near you.

Managing Food Scraps for a Sustainable Food System and the accompanying presentation Composting: Recycling Through Nature make up a three-hour curriculum consisting of four activities. Students will become aware of behavior resulting in food scraps, the importance of healthy soils and how to use composting to manage food scraps and improve soil health. The “Composting: Recycling Through Nature” presentation used in activity three teaches students the basics of composting science and how to assemble a composting pile. This presentation can also be used as a standalone presentation for any age group. Although initially designed for students in grades 6-8, the curriculum can be easily adapted for other grades and the general public. 

This curriculum was developed as a collaborative effort between Ohio EPA and the Mississippi Department of Environmental Quality. 

Garbology interactive site takes students on a journey - into garbage. Along the way, young readers learn which items should be reused or recycled, and which should be composted. Each time a student drags a piece of trash (or a banana peel, or a can) to the right receptacle, an interesting fact appears on the screen. For example, putting the plastic bottle in the recycling calls up this bit of trivia: Americans make enough plastic each year to shrink-wrap Texas. Putting an item in the wrong bin produces comical results. A fun and engaging site, young readers will learn important lessons about our trash, and our world.

This toolkit is designed to help food service establishments and commercial kitchens save money by reducing wasted food and packaging with suggested strategies, templates and case studies. 

Social Marketing for Recycling in Ohio provides an introduction to social marketing for local community recycling programs. Social marketing is a systematic procedure that uses commercial marketing strategies to change behavior. Social marketing activities include setting measurable goals, conducting research about target audiences and developing unique promotional tools for different target audiences.

Social marketing techniques can be applied to a variety of community recycling opportunities, both small and large in scope. For example, social marketing projects may target a single drop-off, a school recycling program or many neighborhoods in a curbside program. The social marketing approach explained in Social Marketing for Recycling in Ohio is community and opportunity-based. It provides local programs with ways to increase recycling one opportunity at a time, which is especially appropriate in communities where resources are limited. For programs with funding available to hire a consultant, the guide provides enough information about social marketing to develop a request for proposal and evaluate submissions.

Social marketing is useful because traditional promotional efforts are often inadequate. Traditional recycling campaigns inform people about the benefits of recycling and how and where people can recycle. Researchers have discovered, however, that just knowing about an activity and its benefits is not often enough to change behavior. Even those who say they believe recycling is the right thing to do often fail to make good with their behavior. Although changing attitudes is the first step toward acquiring support for recycling, more is often needed to change behavior. Social marketing provides a way to discover what motivates people to engage in an activity based on many factors other than attitude change alone. It provides a way to discover people’s perceptions about potential barriers to recycling, some of which may be unique to each recycling opportunity.

It provides ways to discover what behavior modification techniques may increase recycling and ways to design and evaluate promotional campaigns for different target audiences.

In late fall 2017, the Ohio Environmental Protection Agency (Ohio EPA) retained Resource Recycling Systems to develop a low-cost, high-impact evaluation that identifies the current statewide waste stream and supports materials management planning. This evaluation was performed in part to update the findings of Ohio’s previous Waste Characterization Study published in 2004. The new study concluded in 2018, and the associated Economic Impact Potential of Recycling in Ohio report was delivered to Ohio EPA in February 2019.

This new project had three discrete objectives outlined below.

• Utilize current existing data from Ohio information and any other relevant waste characterization studies to provide an accurate description of the present composition of residential and commercial municipal solid waste (MSW) that is disposed within the State of Ohio.
• Assess the economic value of recyclable materials entering the landfills and assess the potential for job creation through the recovery of these recyclable materials.
• Provide recommendations on recyclable materials to target for efficient and effective recovery activities.

Each objective was achieved. Results are summarized below. Please see the full report for complete details.

Waste Characterization

An issue that complicates the development of a waste characterization for the State of Ohio is the evolving ton, a term being used to describe the shift in the overall composition of the municipal solid waste stream over the past 20 years.

Characterization of Statewide Disposed Waste based on National Waste Composition of Residential aterial(Based on Medium Diversion - Residential and Commercial)

Value of Statewide Disposed Waste (based on February 2018 Market Indexes)

Economic Impacts of Recycling

The current value of potentially recyclable materials that are currently landfilled is $260.5 million based on the Midwest Market Indexes in September 2018. Other materials that can be effectively collected as a separate material stream have a value of $88.1 million. It is difficult to project future prices for recycled commodities in the volatile global market.

According to the report, the combined number of jobs that could potentially be created by recycling marketable materials and all material that is currently recyclable but landfilled is 19,799. An additional 1,372 jobs could be created if yard waste and wood wastes were composted. The total jobs that could be potentially created is 21,171.

The cost of avoided disposal of potentially recoverable material, based on the average gate rate of $43.42/ton for disposal, is $85.9 million. Yard waste, food waste and construction and demolition waste wood is disposed at a cost of $148.9 million. Potentially recyclable materials, such as durable and rigid plastics and LDPE films, are disposed at a cost of $40.5 million. The total cost for disposal is $275.3 million.

$275,320,000 Total

Recommendations

• Evaluate the characterization of waste and recyclables on a regular basis to assess progress toward the recovery of greater quantities of recyclables.
• Determine how new products and consumer behavior are impacting the composition of the waste stream.
• Support increased collection of high-value material such as polyethylene terephthalate (PET) and high-density polyethylene (HDPE) containers and metal containers because there are still recoverable quantities in the disposed MSW stream.
• Investigate and support the future collection and markets for materials that are displacing current recovered material, especially in the packaging materials such as flexible packaging, as these materials are growing in volume.
• Measure contamination rates in disposed material at an MRF (for both particulate matter and moisture) as a means of investigating the impact on the value of material.
• Target generator sampling of the most prevalent business types (for example, grocery stores, manufacturing, retail malls, etc.) that generate significant quantities of waste.
• Enhance research into waste generation indicators for certain waste streams, especially food wastes, to improve future understanding of the types of waste generated by different sectors and to develop sampling plans for the identified waste stream.

The Ohio Department of Natural Resource's Division of Recycling and Litter Prevention commissioned the Ohio Glass Recycling Study to improve how Ohio connects those who have glass with those who need glass. Currently Ohio manufacturers use about 110,000 tons of recycled glass per year from Ohio and surrounding states, yet their need is greater, at roughly 275,000 - 295,000 tons per year.

The study, released in May 2011, indicates that Ohio has a huge capacity for glass recovery. Roughly 90 percent of all glass containers consumed in Ohio are disposed of in landfills as opposed to recycled. While glass remains an important part of Ohio's industrial base, there appears to be a disconnect on the value of glass being recovered. Glass continues to go to landfills primarily due to perceived lack of markets and an inefficient system for collection and processing.

Using recycled glass costs less than using raw materials by reducing energy demands. Implementing strategies that can strengthen glass recycling programs across the state can create a competitive advantage for Ohio's manufacturers. Long-term, the division will work with industry stakeholders to establish an infrastructure that will help Ohio manage the value inherent in everything now being lost into landfills. Jobs will also be created throughout the supply chain. Looking forward, the creation of a glass recycling infrastructure represents the first significant step towards establishing Ohio and Ohio's manufacturers as leaders in green business practices that can continue to reap dividends for generations.

Recycling is good business, and it is good policy. Going forward, recycling glass represents an opportunity to begin systemic change that will be felt throughout our economy and our communities.

There are specific industries in Ohio that create, use and/or provide a significant amount of wood waste. The Construction and Demolition Association of Ohio (CDAO) received a grant from the Ohio Department of Natural Resources (ODNR) to conduct a wood waste study, in order to research the quantity and quality of wood waste/biomass circulating in the state of Ohio from all sources of wood. The study had five main goals:

• Identify readily available wood waste sectors, including:

  • Construction and demolition landfills and recyclers

  • Forestry residues

  • Material recovery facilities

  • Compost facilities

  • Other sources

• Identify/quantify what is currently readily available

• Identify general economics

• Perform a limited waste sort to confirm similar studies

• Make conclusions and observations regarding the overall findings

The recently released Wood Waste Markets and Resource(s) Study provides a better understanding of the existing wood waste market(s) in Ohio, including producers, users and estimated volumes. Major sources of wood waste/biomass include but are not limited to:

• Forestry residues

• Construction and demolition debris (C&DD) processors

• Mill residues

• Landfills (both C&D and MSW)

• Other sources (i.e. material recovery facilities, wood manufacturing facilities)

In some instances, such as wood derived from construction and demolition debris, less-than-adequate markets represent an opportunity for increasing the recycling of wood biomass in Ohio. Potential future markets are extensive including fuel uses to manufacturing feedstock. All potential sources may be needed if the state is looking to attract, renovate and/or expand existing industries to Ohio.

For more information, read the entire report or review a summary of the findings.

The Co-Digestion Economic Analysis Tool assesses the initial economic feasibility assessment of food waste co-digestion at wastewater treatment plants for the purpose of biogas production. Co-digestion is when energy-rich organic waste materials (for example, food waste, fats, oil and grease) are added to an anaerobic digester currently processing less energy-rich organic waste (for example, sewage or manure). Co-digestion allows facilities with excess digester capacity to save and make money, while reducing greenhouse gas emissions, providing a renewable energy source and diverting valuable resources from landfills and/or sewer pipes.

The WARM Waste Reduction Model was originally developed for small to moderate-scale waste managers enabling them to understand how their “business-as-usual” waste management practices compare to alternative practices, such as recycling, source reduction or composting, in terms of greenhouse gas emissions and energy use. Its user base has expanded to include various community officials, U.S. EPA WasteWise partners and municipalities interested in learning more about the climate and waste connection. However, the results garnered from using WARM are estimates and the model approach is not appropriate for use in inventories because of the diffuse nature of the emissions and emission reductions within a single emission factor calculated in WARM.
