In April, a few of the Northwest Biosolids members were able to stop by the Lynden wastewater treatment plant, en route to a committee meeting.
The City of Lynden has a compost facility, where they compost ground branches and leaves, sawdust, and biosolids to make a Class A compost that is available for both commercial landscapers and the public, called Biolyn compost. A finely screened compost is sold to their customers, and the coarse version is available for the public to pick up.

Golf course turfgrasses are managed as highly manicured playing fields, maintained to optimize turfgrass health and aesthetic value and, approximately 16,000 golf courses are operated for public or private use in the United States. Frequent fertilization and supplemental irrigation are often used to promote turfgrass health and create an acceptable playing field, yet organic sources of nitrogen (N) are utilized sparingly.
