Waste Management Structures (Solid Waste) Flashcards
wastes resulting from the production and processing of crops and animals or agricultural products, including manures with at least 20% solids, pruning and crop residues wherever
produced
Agricultural solid waste
any item used to improve the compost structure and to increase porosity to allow internal air movement
Bulking agent
weight ratio of carbon to nitrogen
C:N ratio
mixture of an organic waste with amendment(s) or bulking agent(s) in the proper proportions to promote aerobic microbial activity and growth and to achieve optimum temperatures
Compost mix
controlled decomposition of organic matter by micro-organisms, mainly bacteria and fungi, into a humus-like product
Composting
any item added to the compost mixture that alters the moisture content, C:N ratio, or pH
Composting amendment
process where fungi digest the carbons not degraded during composting and further stabilize the nutrients
Curing
site where solid waste is finally discharged and deposited
Disposal site
solid waste or combination of solid waste which because of its quantity, concentration, or physical, chemical or infectious characteristics may: cause, or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness
Hazardous waste
shall refer to the liquid produced when waste undergo decomposition, and when water percolate through solid waste undergoing decomposition; contaminated liquid that contains dissolved and suspended materials
Leachate
interim containment of solid waste after generation and prior to collection for ultimate recovery or disposal
Storage
involves the arrangement of compost mix in long, narrow piles or windrows that are
periodically turned to maintain aerobic conditions
Windrow composting
The pH varies throughout the compost mixture and during the various phases of the composting process. The recommended pH in the compost mixture should be __ – __. Optimum pH control should be accomplished by adding alkaline or acidic materials to the initial mixture.
The pH varies throughout the compost mixture and during the various phases of the composting process. The recommended pH in the compost mixture should be 5.5 – 8.0. Optimum pH control should be accomplished by adding alkaline or acidic materials to the initial mixture.
