Our products go through rigorous end-of-life testing to be certified compostable. Every product that we sell is BPI (Biodegradable Products Institute) certified to meet the ASTM D6400 standards specification. We’ve taken it a step further by field testing our products with the CMA (Compost Manufacturing Alliance). CMA ...
How can you tell if a product is truly compostable? Are all compostable materials really compostable? Are compostable products eco-friendly? ...
Greens and Browns: Composting Input Management Actium Composting equipment allows for environmentally sustainable disposal and reuse of organic materials in the form of compost. ...
The University of British Columbia and the British Columbia Ministry of Agriculture, tested the Envron odor control system for mushroom composting. A local mushroom composting facility was chosen as the test site. ...
Ensuring Pathogenic Die Off SOIL tests for pathogens two times throughout composting transformation process, which takes between six and nine months to complete. ...
Due to environmental concerns and costs related to the alternatives, biosolids composting was selected to produce a Class A/EQ (Exceptional Quality) biosolids product, thus providing expanded opportunities for beneficial use. From the initial feasibility review to operational status, the implementation spanned nine (9) years, starting in 2005. The upgrade to ...
The watery suspension of AGRAGEL exerts no such effects on the eyes of rabbits. Hens' Egg Test The Hen's Egg Test is an alternative test method to reduce animal testing. ...
Since wastewater is a high strength (TSS up to 10,000, FOG up to 3,000, TKN up to 350 and BOD up to 6,000 mg/l, respectively, bioreactors will produce high MLSS up to 11,000 mg/l. Pilot scale studies tested the feasibility of using either flocculation-flotation or membranes for MLSS removal. ...
Little is known about the hydraulics of sloped compost beds having active free and non-flowing zones, and used for runoff erosion and volume control, and heavy metal removal. Water sorption tests on yard waste compost indicated that water transfer between the two zones would be slow (6 hr for a 0.04 m rise). ...
(Columbus, OH) supplies both consumers and landscape contractors with high-quality mulch, compost, soil amendments and topsoil. The company operates several organic recycling facilities throughout the state of Ohio spanning from Columbus (the state’s largest organic recycling facility) to Cleveland. ...
Some compounds were found in high concentrations (Sphagnum moss, compost, oat straw, ferrous sand and clay soil were tested in batch and column experiments. ...
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 ...
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) ...
The influence of 10 wt.% mature compost was tested on the heavy metal leachate emissions from a calcium-rich municipal solid waste incineration air pollution control residue (MSWI APC). Apart from elongated columns (500 and 1250 mm), an otherwise norm compliant European percolation test setup was used. More than 99% of the metals Al, As, Cd, Cr, ...
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. ...
During 48-hour respirometer tests, the compost sample did not dry to the point where respiration was inhibited. ...
