Larimer County Offices, Courts, and District Attorney will be closed February 20, 2017 for the Presidents' Day Holiday. The Landfill will be open.
Critical services at Larimer County are not disrupted by closures.
The three ways to minimize the amount of trash thrown away: Reduce, reuse and recycle.
(See below for definitions of each.)
Alternative daily cover (ADC)
Daily cover (see definition below) other than dirt, such as
crushed glass, tarps or even a spray-on material made from recycled newspapers. The use of ADC is
becoming more common at landfills throughout the country.
Closing the loop
Completing the recycling cycle by buying products that were made with recycled
A soil amendment, or fertilizer, made from the decomposition of organic matter
such as yard waste and food scraps. Many people make compost from such wastes in their own backyard, and
then use it to help their gardens or lawn grow nicely.
Recycling organic matter, such as yard waste and some food scraps, into compost. Usually
composting requires the right mix of materials added together in a pile, kept moist with water and
turned periodically until the material decomposes and becomes compost.
A cover of 6-12 inches of dirt that is put over the trash at the end of each
working day at a sanitary landfill. Daily cover helps keep odors down, keeps pests away,
prevents fires, keeps trash from blowing away and prevents moisture from trickling through
the trash (which can pollute the groundwater below).
To break down into natural elements; decay. For instance, a banana peel thrown on
the ground will look different a couple weeks later because it's decomposing into small parts
and going back into the earth.
Dual stream recycling
A recycling process in which cans and bottles (one stream) are collected separately from paper products (the other stream). Compare with single stream recycling explained below.
An unregulated place where trash is dumped, and the surrounding environment is not
protected or monitored. Dumps used to be common, but are now illegal in the United States.
Water that's beneath the earth's surface between soil and deep layers of rock. This
water supplies springs and wells, and may be used to supply drinking water.
Household hazardous waste (HHW)
Something in your home that could be dangerous that you no longer want. HHW is usually
some type of chemical that may be toxic (poisonous), corrosive (can eat
through skin or material), reactive (can cause a fire or a harmful gas to be
produced if mixed with oxygen or another chemical) or an irritant (can cause soreness
or swelling of your skin, eyes or internal organs). Examples include paint, pesticides, antifreeze,
bleach, etc. HHW should never be thrown away in the trash because it can contaminate the environment.
Instead, take it to the Larimer County Household Hazardous Waste Collection Facility.
A facility at which trash is burned instead of buried in a landfill. (The resulting ash
must still be landfilled.)
A combination of chemicals and water, or a fancy word for "polluted water."
Leachate occurs when chemicals in buried trash
leak down into the groundwater.
Leachate collection system
An underground system of pipes used to collect leachate and make sure it doesn't
get into the groundwater. Although the Larimer County Landfill doesn't have a
leachate collection system like newer landfills do, the groundwater there is tested for
contamination on a regular basis. When leachate is found, it's pumped out and treated to
make sure it doesn't affect others.
Just like the trash bag you might have in your kitchen trashcan,
a landfill's liner keeps trash from leaking, in this case into the groundwater below.
But the Larimer County Landfill was built in 1963 before liners were required,
so it doesn't have a man-made liner. We got lucky, though - our landfill was built on
a layer of dense bedrock called Pierre shale that acts like a natural liner.
A potentially harmful gas released from landfills as trash decomposes. At the
Larimer County Landfill, vents placed around the landfill allow methane and other gases to
escape into the atmosphere. If gases had no way to escape, they could cause underground
fires or explosions. Methane gas is considered a greenhouse gas, one that collects in the
earth's atmosphere and traps heat within the atmosphere.
MRF (pronounced "murf")
Materials Recovery Facility; a place where recyclables are
sorted, processed and shipped out to be made into new materials.
Commonly known as a recycling center.
To make something new out of something old by changing its chemical or physical properties;
the third and least important of the "3 Rs," because although recycling is good, it still
requires energy and creates some pollution to make new items.
To create less trash in the first place; the first and most important of the "3 Rs."
Buying less and using fewer materials in your daily life are ways to reduce.
To use something over and over again; the second most important of the "3 Rs." Reusing
is something you can do in your own home or town. Examples include using an old yogurt
container to store pennies in or donating old clothes to charity.
A landfill that follows rules set by the federal government, including
having an underground liner, a leachate collection system, a method for venting gases
and using daily cover. The Larimer County Landfill is a sanitary landfill.
Single stream recycling
A recycling process in which materials are collected all mixed together with no sorting required by individual recyclers. So cans and bottles can be recycled together with newspaper, cardboard, etc. Compare to dual stream recycling explained above.
Fees charged to dump trash at landfills and waste transfer stations.
A place, often in a rural area, where trash is temporarily collected
and then periodically transported to a landfill or incinerator.
A method of composting food scraps by adding redworms to them in a specially prepared
bin or box.
The act of preventing garbage from being disposed of in landfills
or incinerators by reducing the amount of materials that you use or buy, reusing products, recycling or composting.
A goal that, if met, would result in very little waste being created;
instead, people would find ways to reduce the amount of materials used in the first
place and to reuse or recycle worn or unwanted materials. Zero Waste principles also
apply to hazardous wastes, by eliminating or reducing the use of hazardous materials
