Technology & Licensing

Merrell Bros. is currently bringing two exciting, proprietary biosolids treatment technologies to market all over the United States; Solar-Thermal Pasteurization and Double-Drum Drying. In our 40 years’ experience in the biosolids industry, we have seen nearly every Class A and Class B treatment technology on the market. Several years ago, we set out on a mission to help municipalities across the country by developing alternative options for waste solid management, treatment and marketing. The solutions we have created are forward thinking and a hedge against rising transportation and disposal costs. The two technologies (Solar-Thermal Pasteurization & Double-Drum Drying) provide energy-efficient methods to achieve significant volume reduction in Class A treatment levels. 

In addition to the technology, Merrell Bros. has also developed a Class A biosolids pelletizing apparatus that reduces and incorporates dust into the pellet body, increasing product aesthetic and acceptance, providing flexibility for nutrient profile customization, increasing spread pattern performance in a broadcast application and providing more marketing options. The pelletizing apparatus can either be used in conjunction with our Class A treatment or come in on the backside of other Class A methods. We have been successful at pelletizing a wide range of Class A material and percent solids in our apparatus, without any preconditioning of the biosolids. 

Merrell Bros. can deliver everything from simple licensing to design-build-operation-marketing of facilities. We can help you explore a wide range of options like concurrence and permitting of treatment technology with state regulatory agencies, marketing and distribution scheme, regionalization, registration as a fertilizer and more!
