Apply now for compost reimbursement in Hawai‘i

The Hawai’i Department of Agriculture and Biosecurity Plant Industry Division is now accepting applications for the Compost Reimbursement Program for the 2026 fiscal year.

The program may reimburse agricultural producers for the cost of purchasing compost, including transportation expenses, according to a news release from the Department of Agriculture.

During the 2025 legislative session, the legislature and Gov. Josh Green approved funding for the program totaling $400,000 for fiscal year 2026. Under the program, agricultural operations may apply for reimbursement of up to 50% of compost and compost transportation costs expended between July 1, 2025, and May 1, 2026.

“For many agricultural operations, compost material is a necessity and a major expense,” said Sharon Hurd, chairperson of the Hawai‘i Board of Agriculture and Biosecurity. “The continuation of this program provides significant support for Hawai‘i’s farmers, ranchers and growers.”

Reimbursement applications will be processed in the order received, not to exceed $50,000 per qualified purchaser and as funds are available. The deadline to apply for the reimbursement is May 1, 2026.

To qualify for reimbursement, the compost must be purchased from a certified processor, retailer or wholesaler licensed to do business in Hawai‘i. In addition, certified Hawai‘i processors are limited to those companies regulated under the Hawai‘i Department of Health Solid Waste Management Program.

Qualified agricultural operations include: commercial agriculture, aquacultural facilities, livestock, poultry, apiary and landscaping activities. Applicants must also provide a W-9 tax form, a sample invoice from the applicant’s business and proof of compliance with federal, state and county tax and business regulations.
