The above listed includes trucks that will collect on a daily basis, as well as back up • collection vehicles and_other vehicles designed to collect food waste in larger quantities, or otherwise from yearly special events. Other collection methods that utilize larger van trailers (not listed above) are available should the county need to modify collection protocol for new or larger waste generators. AI{trucks carrying incoming waste materials to be composted at Brooks Compost Facility are weighed on- certifiedtruck scales upon entering the•facility with each toad. ALL MATERIALS COLLECTED IN BROOKS CONTRACTOR',S SPECIALLY-DEIGNED FOOD WASTE COLLECTEO-N TRUCKS ARE HAULED TO-BROOKS COMPOST FACILITY FOR COMPOSTING. Understand that other customer's materials may be included with the load. Daily scale tickets pertaining to the county's waste will be provided upon request. Materials received-with the load that are not.compostable may be-sorted and hauled~to a.landfill-or recycled. Please accept the following as a simple description of the daily operations of Brooks Compost Facility. The compost facility is situated on the Brooks family land that was previously utilized for dairy and agriculture purposes. The facility is located on the same tract of land at 1195 E~eal Road in Goldston that Brooks Contractor manages-and operates. [Various wastes-or "feedstocks" enter our facility and are weighed-to track tonnages and for reporting pur-poses. Wood wastes and other "bulking materials" are stored and used as needed, whereas other nitrogenous materials (such as food waste)' are immediately homogenously mixed to.begin the composting process. The mixture will almost immediately begin a.~temperature-rise and the composting_ process begins. "Windrows" (long, narrow piles-or rows) are formed from the mixture and we let Mother Nature do her work. Our goal as-a commercial compost facility is to speed up nature's processes. We do this by making sure the microbes that are responsible for breaking down organics are given an optima.l-environment to work. When the beneficial decomposing microbes are at an optimal tempera-tune range (131-155 F), harmful microbes and pathogens are destroyed. Windrows are monitored closely and aerated with a "windrow turner" which also inverts the windrow to make sure that all materials reach the proper temperature .requirements. Moisture from the fadlity's stormwater pond is added when needed, ail the while abiding by PFRP (Process to Further Reduce Pathogens) standards in the compost industry. The facility is able to utilize the excess stormwater in cooling down windrows; which provides another opportunity to re-introduce nutrients into the.compost. On average, the active composting phase lasts 3-4 months. The windrows are then moved to large curing piles for stabilization, and will remain there for at least ]. year unless a shorter curing time is required by the end user. Screening the compost to Y~' is the last step before marketing and selling the compost. Oversized materials (like larger pieces of wood) will go back through the process, and may take several cycles to break down. Our compost is sold for use in landscaping, food production, athletic fields, erosion control, and generally as an amendment where poor soil hinders plant growth or more nutrient value is needed.] 7
