2019 Year End Data
In spite of the near-fatal blow delivered on August 13, 2019 when we learned that our anticipated legislative appropriation of $185,000 would not be awarded to the eight schools who applied, the Hui made it to the end of the calendar year with residual funds from the Castle Foundation, Garden Club of Honolulu, and many individuals who donated generously to support our cause. Staff was cut; it was a daily struggle to cover all bases, but the Windward Zero Waste School Hui proved both resilient and productive.
There were 180 school days included in the 2nd semester of 2018-2019 and the 1st semester of 2019-2020. Data is compiled by the calendar year – rather than the school year – to meet the submission requirements of the U.S. Environmental Protection Agency. Zero Waste program diversion data has been submitted since 2013-2014. Internally, data is grouped by semester, so it’s easy to recalculate to reflect a school year if asked.
Food waste diversion
Total food/milk waste collected and processed on five campuses in 2019 was 110,318 pounds, or 55.2 tons. On average over the year, 10% of total food waste was processed by worms; 90% by thermal composting.
Total 2019 compost yield on five campuses: 50.48 cubic yards. Market value @ $270/cu yd = $13,630.
Total 2019 vermicast harvest yield on four campuses: 1.9 cubic yards or 50 cubic feet. Vermicast is sold by weight @ $3/lb. Market value: one cubic foot = 25 lbs x 50 @ $3/lb = $3,750.
Spread the WORM – measurable community outreach
WZWSH advocacy is action-based and results-oriented. With the final closing of the Waikiki Worm Company breeding facility in Wahiawa in 2019, Hui schools currently own the only significant wormstock on Oahu. To spread the Zero Waste practice of vermicomposting to the community, sales of surplus worms to the public was initiated this year. Worms were sold to 104 individuals, three schools, and to seed a major installation at Green Rows Farm in Waimanalo, a total of 54 pounds,10 ounces, with proceeds totalling $8,740. There’s a ripple effect: if each of the 104 new households with worm colonies vermicompost the average family food waste of 7 pounds per week, in 2020, an additional 37,128 pounds of food waste is diverted annually.
WZWSH satellite campus – Manoa Elementary School
With funds vanishing mid-year, several staff members resigned to find more secure employment. Augusto Decastro, who had completed a full year as a WZWSH apprentice, was hired by Manoa Elementary as a Sustainability Coordinator – a PTT (part-time teacher) position – with the understanding that his focus would
be waste management based on the Ka’ohao Protocol. With minimal resources and no budget, Augusto started collecting and composting food/milk waste, logging 15,542 pounds (7.8 tons) in 175 days. The Hui supported this effort by paying for one day of staff help, including Manoa in volume supply buys, and lending equipment. An excellent website for this satellite campus can be found at https://zerowasteschools.net/manoa/. WZWSH operations have proven rock solid. The goal for 2020 is to find a funding source equally as reliable.
