Solid Waste and Renewable Resource Management in Animal Agriculture

Solid Waste

Non-liquid materials produced in animal agriculture that must be managed to protect health and the environment.

Manure Solids

Solid excreta from animals, often mixed with bedding like straw or shavings.

Livestock Mortalities

Carcasses of dead animals that need to be managed properly to prevent disease spread.

Feed Waste

Unconsumed feed and spoiled feed resulting from animal feeding operations.

Segregation

The process of keeping incompatible wastes apart during waste management.

Containment

Using covered bins and equipment to safely store waste and prevent cross-contamination.

Temporary Storage

Methods of storing waste designed to prevent runoff and odor escape.

Physical Characterization

Analyzing waste based on moisture content, particle size, and contaminants.

Biological Characterization

Examining waste for pathogen risks and vector attraction potential.

Chemical/Nutrient Characterization

Identifying nutrient levels (N, P, K) and balance in waste like manure.

Carbon-to-Nitrogen Ratio

A metric used to assess the balance of carbon and nitrogen in composting materials.

Composting

Controlled biological decomposition of organic materials into a stable product.

Incineration

High-temperature combustion that reduces organic waste to ash and gases.

Recycling

Collection and processing of materials into new products to reduce waste.

Burial

Placing waste in the ground to isolate it from the environment.

Anaerobic Digestion

Microbial decomposition without oxygen to produce biogas and digestate.

Leachate

Liquid that drains from solid waste, potentially containing pollutants.

Biosolids

Treated organic materials from wastewater processes that can be land-applied.

Digestate

The solid or liquid material remaining after anaerobic digestion.

Nutrient Management

The practice of matching nutrient inputs from waste to crop needs.

Pathogen Risk

The potential for pathogens from waste to cause disease in humans or animals.

Pollution Prevention

Strategies aimed at preventing nutrient and pathogen contamination of water.

Biosecurity

Measures taken to prevent disease spread within and between animal farms.

Environmental Risks

Potential environmental harm from waste such as water contamination and air emissions.

Operational and Community Risks

Issues that affect farm operations and local communities like odors and pest attraction.
