Municipal Solid Waste (MSW) also called trash, refuse or garbage.
The following are from the Environmental Protection Agency's
Facts and Figures for 2006
Through the combined efforts of individuals, communities, organizations, business
and government involvement the amounts recovered and reused continue to improve.
The three ‘R’s:
EPA: Recycling Information
Reduce: Source Reduction (waste prevention) is the practice of
designing, manufacturing, purchasing, or using materials that are less toxic reducing
the amount or toxicity in trash created as well as reusable (delaying their entry
to the waste stream). This also applies to the production process by conserving
resources and reducing pollution.
Reuse: Reusing items delays their entry to the waste or recycling
streams reducing the resources required to process them.
Recycle: Recycling removes items from the waste stream bound for
disposal sites. This practice saves valuable resources (reusing raw materials) and
improves the environment (not burying or burning hazardous materials).
Recycling solutions vary: Central location drop off sites, Recycling Centers, and
recovery programs of municipal and private waste collection companies.
Collection programs vary in different areas and may involve various curbside separation
and/or Material Recovery Facilities.
The curbside recycling programs require the customer to clean and separate accepted
recyclable materials in either individual containers or a single recycling container
(comingled). Then it is further separated and prepared for transport at a recovery
facility. The advantage of this style of recovery is the percentage recovered and
the cleanliness of the materials. However this style of recovery usually involves
doing the same route up to three times to collect all types of materials (i.e. MSW,
Recyclables and Green Waste). This increases the overall cost of collection as well
as Green House Gas Emissions.
The Material Recovery Facility separates recyclables as the stream(s) are processed. MSW,
along with recyclables collected via other programs, are prepared for transport
to use facilities. MRF facilities also separate biodegradable materials from
the waste stream for mulch and fertilizer use. Finally, what is left is transported
to landfills or incinerator generation facilities. While the initial cost of high-tech
facilities is high, recovery can be maximized as the entire waste stream is exposed
to the recovery process while not increasing long term cost to the company, customer,
or adding significantly to Green House Gas Emissions.
