Resource and Waste Recovery Terms
RESOURCE MANAGEMENT TERMS
Resource Management
Agricultural Residues: Leftover plant materials from farming activities (e.g., corn stalks, wheat straw) that can be repurposed for composting, bioenergy, or animal feed.
Anaerobic Digestion: A biological process that breaks down organic matter—such as food waste—without oxygen, producing biogas (used for energy) and digestate (used as fertilizer).
Biodegradable: Materials that can be broken down naturally by microorganisms into water, carbon dioxide, and biomass.
Biosolids: Nutrient-rich organic materials resulting from the treatment of sewage sludge, often used as soil amendments in agriculture.
Byproduct Synergy: A strategy where waste or byproducts from one process are used as inputs for another, reducing overall waste and improving resource efficiency.
Circular Economy: An economic system aimed at eliminating waste and the continual use of resources through reuse, repair, recycling, and regeneration.
Environmental Impact Assessment (EIA): A process that evaluates the potential environmental effects of a proposed project, including waste management systems.
Extended Producer Responsibility (EPR): A policy approach where producers are given significant responsibility—financial and/or physical—for the treatment or disposal of post-consumer products.
Greywater: Relatively clean wastewater from sinks, showers, and food processing that can be reused for irrigation or cleaning after treatment.
Life Cycle Assessment (LCA): A technique to assess environmental impacts associated with all the stages of a product's life—from raw material extraction through disposal.
Material Recovery Facility (MRF): A specialized plant that receives, separates, and prepares recyclable materials for marketing to end-user manufacturers
Nutrient Recovery: The process of extracting valuable nutrients (like nitrogen and phosphorus) from waste streams for reuse in agriculture.
Organic Waste: Biodegradable waste that comes from plant or animal sources, including food scraps, paper, and yard trimmings.
Raw Manure: Undigested animal feces used as a natural fertilizer. While rich in nutrients, it must be managed carefully to prevent water contamination and pathogen spread.
Resource Recovery: The process of extracting useful materials or energy from waste, such as composting, recycling, or converting waste to energy.
Source Separation: The practice of separating waste materials at the point of generation to improve the efficiency and quality of recycling or composting.
Waste Management
WASTE MANAGEMENT TERMS
Composting: The controlled aerobic decomposition of organic materials (like food scraps and yard waste) into nutrient-rich soil amendments.
Food Loss: The decrease in edible food mass throughout the part of the supply chain that leads to edible food for human consumption, often occurring during production, post-harvest, and processing.
Food Waste: Food that is fit for consumption but is discarded at the retail or consumer level, often due to spoilage, overproduction, or aesthetic standards.
Inedible Food Waste: Parts of food not typically consumed by humans (e.g., peels, bones, shells) that can be composted or used in animal feed or bioenergy.
Landfill Diversion: Strategies and practices aimed at reducing the amount of waste sent to landfills, such as recycling, composting, and food recovery.
Leachate: Liquid that drains from landfills or compost piles, potentially carrying harmful substances into soil and water if not properly managed.
Offal: The internal organs and entrails of a butchered animal, often considered waste but sometimes processed into pet food, fertilizer, or other byproducts.
Recycling: The process of converting waste materials into new materials and objects, reducing the need for virgin resources.
Rendering: A process that converts animal byproducts (like fat, bones, and offal) into usable materials such as tallow, meat and bone meal, and biofuels.
Slaughterhouse Waste: Organic waste generated during animal processing, including blood, bones, and offal, which can be treated through rendering or composting.
Waste Audit: A systematic review of waste generation and disposal practices to identify opportunities for waste reduction and improved resource use.
Waste-to-Energy (WTE): A process that converts non-recyclable waste materials into usable heat, electricity, or fuel through combustion or other methods.
