The feathers can be processed and made into fashion accessories,decorative pieces and building materials. A food processor has found another use for waste water that is saving overheads and bringing in money.
Poultry processor Keystone Foods, Reidsville, North Carolina, uses a rotary press to add value to wastewater by-product by reducing moisture and thus transportation costs. The Keystone Foods facility ships dissolved air flotation by-products to a vendor for composting to make organic soil amendments. By reducing the moisture content of the by-product, shipping costs (and net energy usage) are reduced.
The rotary press reduces total solids from around 90 percent to under 35 percent.
