  • Sector N: Scrap and Waste Recycling
    Industrial Stormwater Fact Sheet Series Sector N: Scrap Recycling and Waste Recycling Facilities U.S. EPA Office of Water EPA-833-F-06-029 February 2021 What is the NPDES stormwater program for industrial activity? Activities, such as material handling and storage, equipment maintenance and cleaning, industrial processing or other operations that occur at industrial facilities are often exposed to stormwater. The runoff from these areas may discharge pollutants directly into nearby waterbodies or indirectly via storm sewer systems, thereby degrading water quality. In 1990, the U.S. Environmental Protection Agency (EPA) developed permitting regulations under the National Pollutant Discharge Elimination System (NPDES) to control stormwater discharges associated with eleven categories of industrial activity. As a result, NPDES permitting authorities, which may be either EPA or a state environmental agency, issue stormwater permits to control runoff from these industrial facilities. What types of industrial facilities are required to obtain permit coverage? This fact sheet specifically discusses stormwater discharges various industries including scrap recycling and waste recycling facilities as defined by Standard Industrial Classification (SIC) Major Group Code 50 (5093). Facilities and products in this group fall under the following categories, all of which require coverage under an industrial stormwater permit: ◆ Scrap and waste recycling facilities (non-source separated, non-liquid recyclable materials) engaged in processing, reclaiming, and wholesale distribution of scrap and waste materials such as ferrous and nonferrous metals, paper, plastic, cardboard, glass, and animal hides. ◆ Waste recycling facilities (liquid recyclable materials) engaged in reclaiming and recycling liquid wastes such as used oil, antifreeze, mineral spirits, and industrial solvents.

  • The Business Case for Zero Waste GM Blueprint Summarizes Waste-Reduction Strategies and Global Landfill-Free Program Updated: Feb
    The Business Case for Zero Waste GM blueprint summarizes waste-reduction strategies and global landfill-free program Updated: Feb. 28, 2018 DETROIT – Industrial facilities in the United States generate and manage about 7.6 billion tons of nonhazardous industrial waste in land disposal units annually, according the U.S. Environmental Protection Agency. General Motors, however, reuses, recycles or composts 84 percent of its worldwide manufacturing waste and has 142 landfill-free facilities. The landfill-free program allows GM to reduce its waste footprint, while creating greater environmental awareness among employees and communities where it makes and sells cars and trucks. The GM workforce is consistently encouraged to find new ways to operate leaner and more efficiently. The following summarizes GM’s blueprint for attaining landfill-free leadership. It is intended to help companies of all sizes and industries reduce waste and create efficiencies. GM Program Overview GM achieved its first landfill-free site at our Flint Engine operations in 2005. The continued progress to 142 global sites has inspired an aspirational goal to have all manufacturing sites send zero waste to landfill. GM has more landfill-free facilities and recycles more waste from its worldwide facilities than any other automaker. GM uses a number of strategies to achieve corporate sustainability goals, but the underlying philosophy is thinking of waste as a resource out of place. The company’s zero-landfill facilities demonstrate this. Waste reduction also often enhances productivity, quality, efficiency and throughput. This is why GM merged its environmental efforts with its manufacturing sustainability goals. The result is a more sustainable company poised to provide products to global customers well into the future.

    Best Practice LCA: End-of-Life Modelling October 28, 2014 Agenda 1. Modelling EoL in LCA 2. Recycled content approach 3. Avoided burden approach 4. Value-corrected substitution 5. PE’s recommendations 6. Current PEF discussions 2 Modelling EoL in LCA 3 Modelling EoL in LCA General challenge • “Allocation” is commonly used to assign burdens associated with the upstream supply chain to each product of multi-output processes. • EoL modelling gives rise to a similar problem due to its multi-functionality – treat waste and produce valuable products (material and/or energy) • Focus on how the burden of virgin material production and the burden of EoL treatment be allocated between the first application in one product system and its subsequent application in the same or another product system. • Chosen allocation approach will affect modelling of other EoL pathways as well (e.g., landfill). 4 Modelling EoL in LCA Most common approaches • Recycled content approach (a.k.a. cut-off, 100/0) • Avoided burden approach (a.k.a. End-of-Life recycling, 0/100) • Value-Corrected Substitution 5 Recycled content approach 6 Recycled content approach General description • Scrap inputs to the product system are modelled as being free of any primary material burden (all assigned to the first life cycle). • The recycling of scrap generated by the product system is not part of the product system and the system boundary is drawn at the point of scrap generation. No credits for subsequent recycling. • When modelling other disposal processes (e.g., incineration with energy recovery, landfill with landfill gas capture), burdens are included, but no credits should be given for energy recovery.

    Five Steps to Natural Yard Care 1. Build healthy soil 2. Plant right for your site 3. Practice smart watering 4. Think twice before using pesticides 5. Practice natural lawn care Homemade Food Scrap Digester Your new digester is ready to use! Collect food scraps, storing them in a container in your kitchen, and once or twice a week, throw the food scraps into the Food Scrap Digester. If odor or fruit fl ies are a problem, you can stockpile bags of brown leaves, coarse sawdust, straw, or shredded paper near the digester and use the material to place a thin layer on top of each new food scrap addition to the digester. No worms need to be added to this digester. Worms will fi nd their way into the digester through the holes and will help break down the food scraps. Harvesting the Compost Depending on your household’s food habits, a digester will fi ll in 6- 12 months. Harvest the compost by shoveling the upper foot or so of Properly composted food scraps can be turned into an excellent undecomposed food off to one side and fertilizer for gardens. However, composting food scraps in an open pile shoveling the dark, soil-like compost or mixed with yard waste can attract some unwanted urban pests— out of the bottom of the digester.
