Development of Horticultural Containers from Anaerobically-digested Cow Manure
Freunds Farm has developed an innovative process that transforms cow manure into valueadded,
biodegradable containers for horticultural use, called CowPotsO. These
CowPotsOturn manure from a burden into a profit center. Work performed to date has
demonstrated that small quantities of pots can be molded from manure that offer the desired
characteristics of biodegradability and decomposability, penetration of plant roots through pot
walls, and nutrient content. However, the solids separation and bio-gas fuel source need to be
researched to improve the efficiency of the manufacturing processs. A horticultural evaluation is
needed after any process change to insure product acceptability in the market place.
The work performed under this grant will characterize the solids separation process and bio-gas
fuel use needed to efficiently run a CowPotsO manufacturing facility. Prototype CowPotsO
will be fabricated using Freunds Farms existing manure digester and pulp molding equipment.
The CowPotsO will be tested in University and farm settings.
This project will give farmers an alternative for managing manure with environmental and
economic benefits-creating jobs and sustaining farms in the process. CowPotsOcan displace
plastic pots, reducing a disposal problem and dependence on foreign oil.
Market studies show that 45% of gardeners are very interested in manure pots, a market
potential of 175 million small pots alone. Other new products, including larger size pots, rolled
mulches, and weed control disks can be developed. Long-term opportunities include technology
transfer agreements and product licensing.
