Home Composting Diversion: Household Level Analysis
The goals of the present study were to (i) verify Parfitt’s (2005) household-level models of home composting diversion, (ii) provide additional insight into how those diversion factors were derived, (iii) extend the modelling approach to consider garden waste in residual and garden waste collections, and (iv) track the performance of compost bins supplied by WRAP (Waste & Resources Action ...

Pilot project cuts odor, cost for humanure compost
Utah Valley Daily Herald Article on the benifits on using micro-pore membrane compost covers when composting highly odorus material. In February of 2009 Utah Valley's North Sewer Distirict conducted a pilot study to determine the effectivness of mirco-pore membrane compost covers in reducing odors from biosolids (sewage sludge) composting. Odor testing was conducted over a term of one month ...

Oxygen Uptake of Soil and Compost Samples
Oxygen Uptake of Soil and Compost Samples The Challenge AER-200 aerobic/anaerobic respirometer is ideally suited to determine in-situ rates of oxygen uptake in soil or compost samples – as may occur in the upper layers of soil under natural atmospheric conditions or in mixed compost reactors. This objective is accomplished by using a double-column reactor configuration as illustrated in Figure ...

Investigations into the possibility to compost paraffincoated packaging materials
Utilisation of biodegradable materials is indispensable for effective economic operation (Soyez, 1998). However, the requirements to be met by the application characteristics sometimes prevent use of such materials. For example, packaging materials for foodstuffs, where protection of the contents is the predominant aim, are required to display hydrophobic properties. Paraffin-coated papers have ...

Stability measurement of Biosolids Compost by Aerobic Respirometry
Oxygen uptake of biosolids compost was measured during both laboratory and full-scale studies. Aerobic respirometry of solid samples of compost provided a precise measure of microbial activity. There was a noticeable decreasing trend in oxygen consumption over 25 days of composting, thereby indicating increasing stability. Moisture content also was found to affect the compost stability. During ...
