Environmental Benefits Fact Sheet on Recycling1 in New Jersey: An Overview for 20042© September 2006 IntroductionMost people are aware that recycling decreases reliance on landfills, incinerators and waste-to-energy facilities. This waste reduction strategy is also critical for protecting the global environment. By reducing the need for "virgin" resources extracted from forests, oil reserves, and mines, we use less energy, reduce greenhouse gases, water pollution, and conserve natural resources. Reducing energy use decreases greenhouse gas emissions because the majority of consumed energy in the United States relies on fossil fuels (i.e., gasoline, diesel, natural gas and coal). Fossil fuels are the most significant source of carbon and other greenhouse gas emissions. Energy conservation also minimizes the need for energy development and production, which are also responsible for significant environmental impacts. Recycling also keeps materials out of landfills, incinerators and waste-to-energy facilities, where water and air contamination can result from leachate, air emissions, and ash residue. By contrast, the steps required to supply recycled materials to industry (i.e., collection, processing and transportation) uses less energy than the steps in supplying virgin materials (i.e., extraction, refining, processing, and transportation). The majority of the energy savings associated with the use of recycled content materials in manufacturing is the result of avoided processing, because recycled materials have already been processed at least once. NERC’s Environmental Benefits Calculator generates estimates of the environmental benefits of New Jersey, based on the tonnages of materials that were recycled, landfilled, or incinerated (includes waste-to-energy). The Calculator is based on per ton figures of the estimated energy use and emissions from several lifecycle analysis studies. The Calculator tailors the results to the amount of materials recycled; as well as the current mix of landfilling, incineration/waste-to-energy in New Jersey. This Fact Sheet summarizes some of the results from the Calculator specific to New Jersey. New Jersey 2004
New Jersey’s municipal and commercial recycling programs collected and supplied 12,007,095 tons of scrap commodities such as paper, glass, metals, plastics, wood, computers, and construction & demolition (C&D) materials for use in the production of new products.
New Jersey recycling reduced greenhouse gas emissions by 2,980,831 metric tons of carbon equivalents (MTCE)3 in a one year period. This is equivalent to approximately 75% of all industrial MTCE emissions generated from fossil fuel combustion in New Jersey and 8% of greenhouse gas emissions, such as carbon dioxide (CO2), methane (CH4), nitrous oxides (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). Curbside recycling alone accounted for a reduction in greenhouse gas emissions of 1,199,136 MTCE per year.
New Jersey’s recycling saved a total of 113,591,379 Million BTUs of energy, equal to 24% of all energy used by industry in New Jersey. This is equivalent to 914,303,928 gallons of gasoline. It represents the amount of energy that would be required to power 1,094,329 homes for one year in New Jersey. Curbside recycling alone saved 30,695,751 Million BTUs of energy.
By recycling 2,481,725 tons of scrap metal and glass in 2004, New Jersey’s recycling efforts reduced the need for virgin materials, including 186,364 tons of limestone, 2,738,294 tons of iron ore, 1,533,445 tons of coal, 187,906 tons of sand, 59,263 tons of soda ash, and 23,127 tons of feldspar. Recycling 1,040,903 tons of newspapers, phone books, office paper, textbooks, magazines and cardboard in 2004, New Jersey resulting in forest carbon sequestration benefits equal to 71,964,347 tree seedlings grown for 10 years. Recycling 1,211,045 tons of all types of paper saved 3,996,449 cubic yards of landfill space. All data reported in this Fact Sheet was calculated from the NERC Environmental Benefits Calculator, 2004. For more detail about the specific environmental benefits attributable to source reduction, reuse, and recycling in New Jersey and for NERC’s free downloadable Calculator, see www.nerc.org. 1 Recycling is defined as the use of scrap or waste material used in place of virgin inputs in the manufacturing process. When a Calculator user indicates that they are “recycling” they are referring to the act of setting the scrap or waste material aside for use in the manufacturing process. Furthermore, when Calculator users indicate that they are "recycling" materials like yard trimmings, food scraps, mixed organics, etc, U.S. EPA calculates the benefit of composting. 2 The most recent data provided by the state environmental agency. 3 Metric tons of carbon equivalent (MTCE) is a unit of measurement that expresses the heat-trapping effects of various greenhouse gas emissions. Another unit of measure sometimes used is metric tons of carbon dioxide equivalent (MTCO2).
