Sterilized, reduced in size and weight and upgraded to a longer lasting (and often more valuable) form of carbon. These are the attributes of biochar production that seem most appealing to the general audience of folks who are tasked with solving waste management issues.
Reduced odors, accelerated composting process, reduced nutrient loss. These are some of the benefits of using biochar in the composting process of waste management operations.
Example 1. Crop Processing Facilities; Rice comes in, the hulls are separated, the grains are dried. Huge piles of hulls remain. The hulls carry disease from the field and are often of very little value to the industry where they came from. Biochar production offers a way to sterilize the rice hull, reduce the size and weight (to make shipping easier), releases heat that can be used on-site to offset or replace the energy used in drying the grains, and the biochar (which is now sterile) can be used directly back into the fields it came from.
Example 2. Municipal Green Waste (MGW) Management; A facility is paid to convert a mixture of green waste (containing plant diseases, insect pests, weeds, pesticide residues, etc.) into something which can re-enter the community. Some of the materials are fantastic candidates for composting, others are a little more problematic and may be better suited to be handled with fire. Biochar production technologies can be used to handle the chosen portion of waste. The biochar material produced can be used to facilitate the proper composting of the remaining wastes.
Example 3. Composting and Manure Management; In-field use such as in high traffic areas can reduce odors and nutrient pollution. In confined spaces biochar can be used with the bedding. Biochar accelerates the composting process, reduces odors, and reduces nutrient loss. In a well balanced compost, the amount of biochar needed to achieve significant positive results is about 5% or less by volume. The pictures below help to illustrate the basics; rice hull is transformed to biochar using a PyroCal 2200 model biochar production machine. While doing so, there is a large amount of heat energy released, which is harvested and used for other purposes.
Biochar Production Technology
Interested in Biochar Production?
Pacific Biochar is proud to assist in providing BiGchar biochar production technologies to the US.
The BiGchar (Black is Green) patented biochar production technology features durability, mobility, and accepts a wide range of feedstocks. Designed and built in Australia by Pyrocal, it has seen many years of development and field deployment and has matured into a tough, efficient, and user friendly machine that can be installed and moved with relative ease.
Nominal feedstock throughput is 1 ton per hour. Biochar production is 300 – 500 lbs per hour depending on feedstock and moisture content. Acceptable feedstocks include: wood chips, green waste, overs, rice hull, corn cob, nut shells and husks, cotton gin trash, pomace, and more.
Pacific Biochar is the project coordinator for BiGchar technology purchases and installments in the North America region. To learn more visit our BiGchar page or to make an inquiry feel free to contact us.
