Composting biodegradable plastic

Article Abstract:

A paper entitled, 'The Influence of Biodegradable Plastics on the Quality of Biogenic Waste Compost,' presents the results of a study concerning the degradation of biodegradable plastics such as Biopol through microbial processes. Biopol was mixed with biowaste in a 70:1 ratio and placed inside a container filled with biowaste, where temperature and moisture were kept constant to achieve optimum conditions. The resulting compost was tested on plant growth, which showed 100% yields, indicating that biodegradable plastics can be successfully composted to produce useful wastes.

Sensible management: composting on the side

Article Abstract:

Laughton Nurseries in Chelmsford, MA which began its composting operations in 1934 for its own use has now turned into a major composting facility. In 1987, leaves and grass clippings from parks and cemeteries including yard trimmings from the Westford neighborhood were brought to the nursery to be composted. Also, the nursery has undertaken a composting project designed to reduce food residual in Boston's wastewater treatment facilities. However, despite the demand for composting, the nursery maintains it as a side business due to the absence of a management staff for it.

McDonald's behind the counter composting pilot

Article Abstract:

McDonald's Corp conducted a 1991 study of the feasibility of composting its paper waste in a way that was compatible with its operations. The result has been the launch of a program in which the company now uses 7,500 tons a year less of packaging than before. The company discovered that 85% of its waste was easily compostable and that it made good economic sense to make the effort once certain logistical difficulties were solved.
