Scope

Scope: This standard specifies the method for determining the 4-day respiratory activity parameters in the evaluation of the biodegradability of municipal solid waste. If necessary, the evaluation period can be extended to 7 days, and the determination shall be carried out in accordance with the methods specified in this standard. This standard is used to evaluate the biodegradability of municipal solid waste under aerobic conditions and to determine the aerobic respiratory activity of municipal solid waste. This standard is applicable to municipal solid waste generated from sources and at logistics nodes of municipal solid waste. This standard can be used to evaluate the composting maturity of waste after biological treatment (composting). This standard is not applicable to waste directly from anaerobic treatment, as its physical and chemical properties inhibit biological activity (e.g., stabilization caused by calcium ions, acidification, and highly reactive substances). For municipal solid waste with a pH value below 6 or above 9, this standard is not applicable. If these materials need to be tested under special circumstances, the method should be modified accordingly. Main technical content: The 4-day respiratory activity determination method in the laboratory is adopted. Respiratory activity can be measured by measuring the oxygen consumed or the carbon dioxide produced, and expressed in mg O2/g dry matter (DM). The basic principle of this method is the same as that of the Austrian standard ?NORM S 2027-4:2012.
