Biosolids

Biosolids are the semi-solid by-products of wastewater treatment. The EPA classifies all biosolids as either unstabilized, Class B, or Class A. Unstabilized biosolids have undergone minimal treatment and processing. Class B Biosolids have been stabilized using one of several approved methods of treatment so they are safe for beneficial use. They are not as processed as Class A Biosolids and therefore have more restrictions on distribution and use, but can be a cost effective method of residuals management. We have expertise in Class B Biosolids management including analysis, treatment options, site permitting, and full program management. Class A biosolids are highly processed achieving significant requirements regarding treatment and must conform to strict parameters using analytical testing. Biosolids compost is an example of a Class A material, as are biosolids pellets.

Biosolids Pellets

An increasing trend in biosolids management is to treat the processed material with heat and effectively dry the solids into a pelletized form.  The resulting pellet is an excellent material to market as it has a more diverse set of end uses and is easier to transport and apply.  We are experts in the realm of marketing biosolids pellets and manage material from the largest pellet manufacturing plants in New England.  If you produce biosolids pellets, or are interested in learning more about the options for production or management, contact us today!

Compost

Compost is the product resulting from the controlled biological decomposition of organic material that has been stabilized through the generation of heat and finished to the point it is beneficial for plant growth.  We know compost and we love to market it!  Thanks to our efforts, over 1,000,000 cubic yards of earthlife™ Compost have been used to improve soil health and plant growth throughout the Northeast.   earthlife™ Compost offers consistent quality, high organic content, microbial life and valuable slow-release nutrients.

Casella Organics sells compost from multiple facilities located throughout New England that use a variety of feedstocks.  We specialize in assisting compost facilities with the distribution of their end-product to maximize value.

 

Food Scraps

Often considerd the "final frontier" of organics recyling, food scraps are the leftover food materials in our waste stream.  Generated by everyone from individuals to institutions, they are challenging to collect, process and beneficially use.  We are working on a number of service options and innovative programs to capture this valuable stream of nutrients including anaerobic digestion.  

Leaf, Yard, and Wood Waste

Yard trimmings and wood waste make up a significant portion of the "waste" generated in our society.  Luckily there are many programs designed to collect and reuse this valuable material.  Many municipalites offer leaf and yard collection or composting to residents, and a number of private businesses offer tree services including wood products and mulch production.  We manage this type of organic material in composting and value-added processing.

Liming Agents

We are experts in finding beneficial agricultural use for residuals with liming value.  Utilizing analytical results and our experience in soil science, we are able to develop custom programs and blends for materials containing high pH and other characteristics similar to conventional lime that drive cost effective management programs.

Liquid (FOG)

FOG stands for “Fats, Oils and Grease” and is found in your kitchen or garage. The main contribution of FOG is from discharge of used grease from cooking processes, but can also be caused by machinery lubricants discharged into floor drains. Many of the foods we eat contain FOG; these include meats, sauces, salad dressings, deep-fried dishes, cookies, pastries, butter and many others. Generally, food scraps washed down the drain also contribute to FOG in the sewers. Grease accumulation in the sewer system causes obstruction by constricting flow of the sewer pipes, and interfering with the normal operation of your community waste-water treatment system.

Short Paper Fiber

Short Paper Fiber is a by-product of paper manufacturing, produced by removing fibers from the process that are too short to bind together to make paper.   Rather than discard these "rejects" we find ways to beneficially use them and return their nutrients and organic matter to the soil.  SPF can vary widely depending on the paper mill, the mill feedstocks, and the production process used.  We are experienced in analyzing spf to find the best and most economical way to reuse it.

Wood Ash

Wood Ash is produced from the combustion of clean wood and bark products to generate power. There are many types and sizes of boilers that burn biomass to generate power.  We are experienced in managing ash from a variety of them.  The resulting ash is an agricultural soil amendment ideal for balancing soil pH and enhancing nutrient levels. Wood Ash can contain significant amounts of magnesium, potassium, and many other micronutrients important to healthy crop production. Since 1983, Wood Ash provided by Casella Organics has been chosen by farmers to increase soil pH, improve soil fertility, and increase crop yield. Wood Ash is easily applied with conventional lime or manure spreading equipment.  Visit our products section to learn more about our innovative programs to put wood ash to use and complete the cycle of using wood for energy - but returning valuable nutrients to the soil.
