Circular Economy

Waste leaves. Soil and fuel come back.

About 86% of Unguja’s municipal waste is organic. Hangaya turns that stream into compost, soil and fertilizer at the Matemwe Organics Yard, then sells it back to the gardens it came from. Phase 2 takes sorted plastic and makes diesel-range oil for hotel generators — at a discount to pump diesel. Carbon Programs are not the product. The product is what the hotel can use and show.

A Story The Guest Can Walk Through

North-coast resorts are selling the same beach. What they cannot copy is a closed loop on their own grounds: clippings and kitchen greens collected, composted on-island, and returned as soil for the same palms and beds. Sustainability pages that only mention a distant landfill or a future credit do not photograph. A garden fed by the hotel’s own waste does.

Hangaya writes the loop into the landscape contract so the grounds team and the sustainability manager are on the same invoice. Use it on the website, in the welcome book, and on a small garden sign if the hotel wants one. We do not invent numbers for their ESG report. We give them a visible practice.

Phases

Phase 1 — Matemwe Organics Yard

Most of the bin is green. We start there.

Hangaya collects kitchen and garden waste from hotels and villas on a scheduled run. At the Matemwe Organics Yard that material becomes compost, planting soil and fertilizer. The same hotel buys it back for beds, lawns and new landscape work. Nutrients stay on the property instead of leaving for Kibele.

What the hotel does: separate wet organics from plastic and residual at source. What Hangaya does: collect, process, return soil. Landscape design, install and maintenance sit on the same team — so the compost has a job the week it is ready.

Collection pricing is quoted per property. It is not published here. Ask for a site visit.

Phase 2 — Plastic to Generator Fuel

After organics are moving, Hangaya takes the hotel’s sorted plastic bottles and film that are fit for the kiln. Pyrolysis makes a diesel-range oil — not pump diesel off the shelf, and not bunker oil. A distilled cut is for generators, boats and plant. The hotel buys it back at a discount to imported diesel. Hangaya’s own sets burn the first liters so the spec is proven before a guest-facing generator does.

Phase 2 follows Phase 1. We do not ask a hotel to wait for a kiln before their garden waste has a home.

Start With a Walk

01 — Grounds and sustainability walk the property with Hangaya.

02 — We map organics volume and how waste is separated today.

03 — Collection starts. Compost comes back into the same beds.

04 — When the fuel module is online, plastic that is already being set aside has a buyer.
