The UBC Dairy and Education Research Centre recently installed an innovative system that separates sand used for dairy cattle bedding from the liquid and solid fractions of their manure. The sand is then cleaned and reused as bedding , while the liquid and solid fractions are eventually used on the Centre’s fields to support grass and corn production.
Besides saving the Centre money by continuously purchasing new bedding, the sand separator also provides a number of environmentally sustainable benefits. By separating out the sand, less heavy equipment is needed to spread the sand on the fields, which translates to less soil compaction less labor, and a reduced carbon footprint as less gas is used in the tractors. The system should pay for itself within seven years.
“It’s working beyond our best expectations,” said Jim Thompson, Director, the UBC Dairy Education and Research Centre.
