Frequently Asked Questions
The SlurryCarb™ technology beneficially reuses the energy content contained within biosolids to produce renewable energy.
Who owns the technology?
EnerTech owns the SlurryCarb™ technology. The company has been issued multiple U.S. and international patents, several specifically encompassing the SlurryCarb™ process.
How is this process different than direct thermal drying?
The SlurryCarb™ process does not attempt to evaporate water from biosolids like thermal drying. Instead, biosolids are pressurized to maintain a liquid state throughout processing and heated to a reaction temperature that enables the biosolids to break down into carbon and light gases, resulting in a condensed slurry with molecules that are very high in energy. Excess moisture is then extracted from the slurry, producing a renewable fuel, called E-fuel. E-Fuel contains a high energy content and can be used to generate energy in lieu of fossil fuels.
Utilizing this patented method, the SlurryCarb™ process uses two thirds less energy than direct heat drying options, and produces a high-quality final fuel product.
What are SlurryCarb™'s advantages over incineration?
New incineration facilities are difficult to permit and costly to construct. They often require supplemental fuel to burn the biosolids, adding to the cost due to greater than ever fuel prices. Most importantly, incineration is not "beneficial reuse" and fails to take advantage of the energy content within biosolids to produce renewable fuel.
The SlurryCarb™ technology does not simply dispose of biosolids, but converts what is essentially a waste product into a renewable fuel that can be used to benefit society and reduce the environmental impact of burning fossil fuels.
Why should our agency consider the SlurryCarb™ process?
Current biosolids management practices continue to face increasing resistance and have led to legislation designed to ban or minimize their use. As a result, capacities are diminishing and the costs associated with these practices are rising. States such as California have seen the land application of biosolids banned or seriously regulated throughout the state.
The SlurryCarb™ technology offers agencies a new, environmentally friendly option in building a diversified biosolids management portfolio. The technology can guarantee a long-term, predictable price for biosolids management with the potential for significant capital and operating cost savings.
What feedstocks work with this technology?
The technology can be tailored to produce a quality renewable fuel from a wide variety of high-moisture feedstocks. Using our Process Development Unit, we have demonstrated that the technology can successfully process any of the following feedstocks:
- Biosolids (also known as Municipal Sewage Sludge)
- Agricultural Wastes and Residues
- Animal Manure and Feeding Operations Wastes
Please contact us if you have questions about a particular feedstock.
Can we test your process on our material?
Yes. Our Process Development Unit (PDU) in Atlanta is designed to test the SlurryCarb™ process on a variety of feedstocks.
Will this process produce odors?
The SlurryCarb™ process is designed to contain odors by keeping biosolids enclosed throughout the process with minimal exposure to open air. As a result, odors produced by the SlurryCarb™ process are significantly reduced.
