Standard Test Method for Determining Biodegradability of Materials Exposed to Source-Separated Organic Municipal Solid Waste Mesophilic Composting Conditions by Respirometry

Importancia y uso:

5.1 MSW composting is considered an important component in the overall solid waste management strategy. The volume reduction achieved by composting, combined with the production of a usable end product (for example, compost as a soil amendment), has resulted in municipalities analyzing and selecting source-separated organic MSW composting as an alternative to landfill disposal of biodegradable organic materials. This standard provides a method to analyze and determine the effect of materials on the compost process and the performance, utility, and feasibility of the composting process as a method for managing organic solid waste material.5 Using this method, key parameters of process performance, including theoretical oxygen uptake (ThOU) and theoretical carbon dioxide production (ThCO₂P) are determined.

5.2 This test method provides a simulation of the overall compost process while maintaining reproducibility. Exposing the test material with several other types of organic materials that are typically in MSW provides an environment which provides the key characteristics of the composting process, including direct measurement of organism respiration.
