Waste Reduction

Waste Reduction


Waste reduction, also known as source reduction, is the practice of using less material and energy to minimize waste generation and preserve natural resources. Waste reduction is broader in scope than recycling and incorporates ways to prevent materials from ending up as waste before they reach the recycling stage. Waste reduction includes reusing products such as plastic and glass containers, purchasing more durable products, and using reusable products, such as dishrags instead of paper towels. Donating products, from office equipment to eyeglasses and clothing, reduces the amount of material manufactured overall. Purchasing products that replace hazardous materials with biodegradable ingredients reduces pollution as well as waste. In general, waste reduction offers several environmental benefits. Greater efficiency in the production and use of products means less energy consumption, resulting in less pollution. More natural resources are preserved. Products using less hazardous materials are used. Finally, less solid waste ends up in landfills.

Waste reduction also means economic savings. Fewer materials and less energy is used when waste-reduction practices are applied. Rather than using the traditional cradle-to-grave approach, a cradle-to-cradle system is adopted. In this cradle-to-cradle system, also called industrial ecology, products are not used for a finite length of time. Instead of disposing of materials, or the components of a product after a single use, products are passed on for further uses. This is considered a flow of materials. This can be applied within an organization, or between organizations that may be considered unrelated, on a cooperative basis. For example, a cotton manufacturer sends its unwanted scraps to an upholsterer, who uses the scraps as stuffing in chairs. When the life span of the chair is reached, the materials are returned to the manufacturer, who reuses the parts with endurance. The damaged upholstery, which was originally created using nonhazardous materials, is sold to a local farmer who uses it in composting. Money is also saved through reduced purchasing. Waste-disposal costs are decreased because fewer materials end up as waste.

Waste can be reduced by individuals, businesses, institutions such as hospitals or educational facilities, organizations, municipalities, or government agencies. There are several ways individuals can practice waste reduction: (1) Reusing products. This could mean reusing file folders rather than throwing them away after one use, or refilling water bottles; (2) Using products more efficiently. This could mean using both sides of paper in photocopying; and (3) Donating or exchanging products or materials that may seem useless, but that another party may find valuable. For example, the chair manufacturer mentioned above had no internal use for the scrap upholstery leftover after recycling the more durable parts of the used chairs. However, a cooperative agreement with a local farmer allowed the scraps to be used once again, benefiting the farmer by adding to his compost.


The EPA's WasteWise Program

The Environmental Protection Agency (EPA) lists waste reduction and reuse as top priorities in its solid waste management hierarchy, followed by recycling, composting, waste-to-energy , and landfilling . Many governments and businesses have adopted the practice of waste reduction.

The EPA offers a free, comprehensive waste-reduction program to businesses, organizations, and municipalities. The program, called WasteWise, offers educational and technical assistance in developing, executing, and measuring waste-reduction activities. Through WasteWise, groups can design and maintain a waste-reduction program that is flexible to their specific needs. The nationwide program was started in 1994, and it had over eleven hundred participating partners in 2002.

Large corporations, universities, and cities across the country have seen significant benefits, both economically and environmentally, by using WasteWise.


The National Recycling Coalition Recommendations

The National Recycling Coalition lists several steps that purchasing departments of organizations can use in their waste-reduction strategies:

  1. Reduce product use. Adopt the practice of printing on both sides of office paper.
  2. Rent or lease products or equipment. This includes leasing, rather than purchasing, equipment such as photocopiers, which can become obsolete, leaving the organization with old, unnecessary, and sometimes hazardous equipment to discard.
  3. Purchase remanufactured or rebuilt products, or products that can be refurbished.
  4. Purchase more durable products. Higher-quality products typically have a longer life cycle.
  5. Purchase products that use nonhazardous materials. Nonhazardous materials are safer for individuals and landfills.
  6. Purchase returnable, reusable, or refillable products. For instance, transport containers can be reused.
  7. Purchase products in bulk.
  8. Purchase products that reuse packaging or use less packaging.
  9. Share and reuse resources within the organization. Companies can implement an internal computer equipment and office supply exchange before purchasing new products.

The EPA reports that 232 million pounds of waste were generated in 2000. The amount of waste produced per person has grown over the last thirty-five years, from 2.7 to 4.6 pounds per day. In 1999, waste reduction saved over fifty million tons of municipal solid waste from being dumped into landfills.

ZERO EMISSIONS

In natural ecosystems, what is waste for one species is food for another. The concept of zero emissions, first elucidated in the early 1990s by Gunter Pauli, applies this principle to business endeavors and is being tested in Burlington, Vermont. At a 3,200 square meter eco-industrial complex enclosing a number of greenhouses. Waste heat from an existing power plant, fueled by discarded Christmas trees, will warm the greenhouses and fire up the brew kettle for a micro-brewery. Pilot tests have shown that "wastes" from the brewing process can be efficiently transformed into nutritious growing medium for marketable mushrooms, salad greens and fish. What remains can be sold as cattle feed and soil amendment.

Waste Reduction

Waste reduction


Waste reduction aims to reduce environmental pollution by minimizing the generation of waste. It is also often an economically viable option because it requires an efficient use of raw materials. Waste-reduction methods include modifying industrial processes to reduce the amount of waste residue, changing raw materials, or recycling or reusing waste sources.

It is more difficult to alter existing industrial processes than it is to incorporate waste-reduction technologies into new operations. Large-scale changes in production equipment are essential to achieving waste reduction. Proper handling of materials and fugitive emissions reduction, as well as plugging leaks and preventing spills, all help in waste reduction. Process equipment must be checked on a regular basis for corrosion, vibrations, and leaks. Increases in automation and the prevention of vapor losses also help reduce waste generation.

Changes in what an industry puts into a process can be used to reduce the amount of waste generated. One example is the substitution of raw materials such as water to clean a part instead of solvents. End-products can also be modified to help reduce waste. Another aspect of waste reduction is the control of fugitive emissions by placing a floating roof on open tanks, for example. Other waste-reduction options include the installation of condensers, automatic tank covers, and increasing tank heights. But these and other decisions on waste reduction very much depend on the size and structure of a company.
