  • Field Testing Protocol For Compostable Packaging

    Compostable product disintegration trials conducted in British Columbia help lay groundwork for open source, field testing protocol. Compostable packaging holds great promise to aid in diverting food waste from landfill. However, even when certified compostable, the products disintegrate differently across facility types. A growing number of composting facilities see potential for ...

  • Dry matter mass balance estimates for composted feedlot manure

    Accurate dry matter mass balance (DMMB) estimates are important if knowledge of nutrient component changes on a mass basis is required for manure handling practices. We compared four methods of estimating DMMB during composting of solid feedlot manure. A manure stockpiling treatment was included for comparison. A method which used carbon (C) concentration to calculate organic matter, and hence ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak’s crews put materials through a Vermeer tub ...

  • Canadian Composting Industry on the Grow

    Organic residuals continue to represent one of the largest untapped portions of the residential and industrial waste streams in Canada. However, this will not continue for much longer. Throughout Canada, programs have been or are about to be established that will capture organic materials and, through composting, transform them into value-added products for use in a multitude of applications. The ...

  • Phosphorus And Compost Use Dynamics

    Organic forms of phosphorus, such as biosolids and compost products, contain low to very low levels of water extractable phosphorus, but increasingly are regulated like inorganic P sources. Phosphorus is one of the 16 essential plant nutrients, and is considered one of the three major plant nutrients (along with nitrogen and potassium). Phosphorus is not only important in root development, but ...

  • Troubleshooting the Compost Pile

    While composting is a biological process, we as composters must provide the microorganisms that do the work with the conditions they need to do their job. If there is a problem with the system, then look at it from the point of view of the microbe. What does that microbe need to function, and why isn’t it functioning correctly? Microorganisms need a source of energy organic feedstocks to feed on ...

  • 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 ...

  • Of biodegradable, compostable, paper plates and marketing

    What if I told you there was no such thing as a biodegradable product? Would it bring to mind images of products you have seen at the local store that are promoted as biodegradable? Would you think I was swimming out of the mainstream? Well according to the FTC, in many cases, it just may be true if you are being marketed a biodegradable product and the seller doesn’t qualify that claim. On June ...


  • Composting of vegetable waste in subtropical climates

    This experiment examined the possibility of using composting as a method of waste disposal in subtropical countries, such as the United Arab Emirates (UAE), where temperatures are high and humidity is low. In order to simulate conditions in the UAE, a representative mixture of wastes generated in the UAE was prepared and tested at ambient temperatures resembling those of subtropical countries. ...
