organizations and facilities are committing to the long-term goal of “zero
waste.” Planning and executing for Zero
Waste presents significant challenges to an organization.
first step is to evaluate opportunities to reduce the amount of waste generated.
Key initiatives in zero waste planning are reducing incoming packaging and
cutting down on the total amount of food wasted. According to LeanPath,
a waste tracking technology company, 4-10% of food purchased ends up as waste
due to overproduction, spoilage, expiration or trimmings. Finding ways of
reducing both pre-consumer waste in the kitchen and post-consumer waste, food
that is not consumed and thrown in the trash, is important to a zero waste
Pulped and dewatered waste material
second step is to treat as much waste as possible on site by using the least
amount of non-compostable material possible. Food waste composting must be
planned, taking into consideration the location of your facility—urban
locations have less open space than rural locations and must plan accordingly
with creative solutions.
Pulpers and DeHydrator systems can can play a vital role in the total zero waste plan. Pulpers alone can reduce waste by 8 to 1, turning waste into a semi-dry pulp. A DeHydrator can then draw off all the remaining liquid, reducing waste material an additional 90%. The end product
can be hauled offsite to a commercial composter or, as in the case of many
rural universities, composted on site.
cost savings realized can in many cases offset the cost of equipment—to learn

With their history as the university with oldest endowed
sustainability program in the country, it’s no surprise that the school asked
Somat to assist with their aggressive plans toward a goal of zero waste and
carbon neutrality. UNH utilizes multiple
Somat Close Coupled Pulpers and Hydraextractor systems as part of their waste
reduction and composting program. Placed in each dining hall, these foodservice
waste units provide a convenient means to reduce compostable waste at the
Somat waste reduction equipment is a part of meeting the challenge.
