The Solution

A recycling solution that transforms fresh food that supermarkets cannot sell or donate into a fertilizer (Harvest to Harvest) which returns nutrients to the soil or into a highly palatable pet food ingredient.

Case Study

CSS recovers unsold food from supermarkets before they go to waste, preserving the “cold chain” and hydrolyzing the food in only three hours using its patented, proprietary enzymatic digestion technology. The fruits, vegetables and meats processed in this way produce high-quality liquid fertilizers that make farming operations more productive and sustainable, as well as healthy, highly palatable pet food ingredients.

CSS products contain complex forms of nutrients, including carbohydrates, amino acids (proteins), organic acids, and fats. These complex elements of nutrition are a source of energy for soil organisms and plants and a great source of organic matter.

Harvest to Harvest fertilizers are 100% pathogen free and safe for use on all crops.
