  • Potential pollutants from farm, food and yard waste composts at differing ages: Part I. physical and chemical properties

    There is little information about the changes in physical and chemical properties of compost as a function of compost feedstocks and age of the compost mixture. As a consequence of this gap, the potential of compost to serve as a pollutant source relative to compost age (from initial mixing of raw feedstocks to mature compost) and feedstocks (i.e. % of food, manure, bedding, leaves, etc.) during ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

  • Design and performance of a simulated feedstock for composting experiments

    This paper reviews the composition and performance of simulated feedstock mixtures previously employed in composting research, and presents a new simulated feedstock. The new feedstock was prepared using readily available dry ingredients - ostrich feed pellets, office paper, finished compost and woodchips - representing the substrate, amendment, seed, and bulking agent components of a composting ...

  • Composters Build Strong Links to California Farms

    The rapidly increasing amounts of compost applied to California farms can be traced to numerous factors — better crops, fewer disease problems, greater emphasis on product quality, mandated state recycling goals, savings in disposal costs and savings in chemical inputs. And then there’s the factor of friendship, longtime personal relationships that build trust between composters and farm ...

  • Can Composting BMPS Reduce Air Emissions?

    Imagine a scenario where all yard trimmings collected for recycling have to be received, processed and composted under the cover of a building. It would be tough for most yard trimmings composting facilities to survive the expense. Yet this situation could have occurred in Southern California. At one point, the South Coast ...

  • Fires at Composting Facilities: Causes and Conditions

    The subject of fires at composting facilities is a bad news/good news situation. The bad news is that fires are more common than we realize. Ask a group of facility operators if they have had to deal with a fire, and the majority will quietly admit they have. The good news is that we don’t realize that fires are fairly common at composting facilities. Most are neither frequent nor destructive ...

  • Review of current European practice of MBT compost-like output use and application to land in relation to environmental protection

    Mechanical-Biological Treatment (MBT) is often a key element in National Strategies for the diversion of Biodegradable Municipal Waste (BMW) from landfill. Unlike incineration, it provides flexibility in the system, which is important in those Member States where the system will have to undergo widespread changes in the amount and quality of residual waste that is dealt with. The main objectives ...

  • Contained Composting Systems Rewiew

    Having gained success in recycling yard trimmings, composters and recycling coordinators are reaching deeper into the organic residuals pile to capture other feedstocks. In particular, their sights are set on source separated food materials, from institutions (e.g. schools, hospitals), grocery stores and produce markets, food processors and commercial food service facilities (e.g. restaurants). A ...
