One of the global concerns on farms, compost operations, and municipal waste facilities is measuring the activity and efficacy of their microbial digestion processes for organic matter. To help with this, we have investigated the efficacy of Culbac® products to enhance and improve the digestion process and therefore to improve the return on investment for composting operations and to affect bio-gas formation.
Culbac® additives are biochemical agents that are introduced to anaerobic digesters to stimulate microbial growth and metabolism and catalyze key biochemical reactions conducive to vigorous digestion. We use a formulation with Lactobacillus to enhance anaerobic digestion. Our products have been tested to provide support for fermentor bacterial organisms, growth factors, metabolic intermediates, enzymes, precursors of key basal materials, etc. that are not efficiently generated during most anaerobic fermentation processes.
Studies show adding low concentrations of Culbac® products substantially improved the high-rate digestion of sewage sludge at mesophilic temperatures positively impacting methane yield, methane production rate, and volatile solids reduction percentage differences, and effluent volatile acids.
At high-rate loading and detention time conditions, stable digestion can be carried out at much higher loading and reduced detention times than conventional conditions with Culbac® additive treatment while maintaining effluent quality and gas production, thereby increasing the waste treatment capacity of existing operations.
Culbac® Compost Aid
Culbac® Compost Aid is an all-natural, non-toxic compost treatment is an easy-to-use, antioxidant-rich additive for waste treatment, composting, and digestion of organic matter. This product is applied as a liquid and accelerates the digestion of organic matter in anaerobic digestors, in the field or in pits, impacts methane yield and methane production rates in anaerobic digesters and minimizes processing time to facilitate higher throughput for waste treatment.
Here are some studies highlighting examples of results from our products.
Study summaries coming soon!
The high-rate digestion of sludge at mesophilic temperatures was substantially improved by the use of low concentrations of the Culbac® product.
In swine operations, Culbac® can minimize foaming in the pit.
Digesters with appropriate bacteria to enhance methane gas production was compared between treated and untreated over a 7-day period. Digesters with Culbac® product inclusion demonstrated increased gas production. Were able to process waste at twice the rate and with significant decrease in odor.
