Compost stability

Article Abstract:

Compost stability is definedby its biological property of microbial activity. A measure of compost stability serves as an indicator for quality control. Microbial activity can bemeasured using dissolved oxygen meter respirometry to measure the decrease in partial oxygen pressure in a closed system over time. The method is quick, economical and ideal for on-site testing of compost stability. However, samplesneed to be preincubated overnight to yield accurate results.

Pallets team up with grass clippings

Article Abstract:

A new technique in composting grass clippings which also solves excess pallet landfill problems is presented. Pallets are used as an alternative carbon source in recycling grass clippings. A local pallet recycler has provided assistance, particularly in removing nails from the pallets. The turning process and the aeration time for organic matter is sped up by its utilization of smaller windrows.
