Methane is a potent greenhouse gas with a global warming potential 25 times higher than carbon dioxide. It is primarily released from landfills, wastewater treatment plants, and livestock manure management.

Landfills are the primary source of methane emissions from waste management. When organic waste decomposes in the absence of oxygen, it produces methane and other greenhouse gases.

Composting is the process of breaking down organic waste into a nutrient-rich soil amendment. It reduces methane emissions by diverting organic waste from landfills and allowing it to decompose in the presence of oxygen, producing carbon dioxide instead of methane.

Incineration of waste primarily releases carbon dioxide, a greenhouse gas that contributes to global warming. However, incineration can also emit other pollutants, such as particulate matter, heavy metals, and dioxins.

Recycling is the process of converting waste materials into new materials and objects. It reduces carbon dioxide emissions by saving the energy and resources required to extract and process virgin materials.

The production of cement is a major source of carbon dioxide emissions. During the manufacturing process, limestone is heated at high temperatures, releasing carbon dioxide into the atmosphere.

Composting reduces nitrous oxide emissions by promoting the conversion of nitrogen compounds into nitrogen gas, which is a harmless component of the atmosphere.

The production of plastics releases hydrofluorocarbons, which are potent greenhouse gases with a global warming potential thousands of times higher than carbon dioxide.

Recycling plastics reduces hydrofluorocarbon emissions by diverting plastic waste from landfills and incineration, where they would release these potent greenhouse gases into the atmosphere.

The production of aluminum is a major source of carbon dioxide emissions. During the smelting process, electricity is used to separate aluminum from its ore, releasing carbon dioxide into the atmosphere.

Recycling aluminum reduces carbon dioxide emissions by saving the energy required to extract and process virgin aluminum. Recycled aluminum can be used to produce new aluminum products with significantly lower carbon emissions.

The production of steel is a major source of carbon dioxide emissions. During the manufacturing process, iron ore is heated at high temperatures in the presence of carbon, releasing carbon dioxide into the atmosphere.

Recycling steel reduces carbon dioxide emissions by saving the energy required to extract and process virgin iron ore. Recycled steel can be used to produce new steel products with significantly lower carbon emissions.

The production of paper is a major source of carbon dioxide emissions. During the manufacturing process, trees are harvested and processed, releasing carbon dioxide into the atmosphere. Additionally, the use of fossil fuels in paper production contributes to carbon dioxide emissions.

Recycling paper reduces carbon dioxide emissions by saving the energy required to extract and process virgin timber. Recycled paper can be used to produce new paper products with significantly lower carbon emissions.
