Compost,Engineered

Green Waste XL, installed on site. Organic and green waste is processed where it falls, without transport, transfer stations or landfill.

Request a pilot

Waste doesn't leave the site. It becomes soil.

CompostEgo processes organic and green waste where it is produced, and reports every condition inside the chamber to the people accountable for it.

The machine

Eighteen components, one sealed cabinet.

Scroll to assemble it, then look inside — through shredding, aeration and six weeks of measured composting, to the drawer.

preparing components
01 / Components

Eighteen parts, one enclosure

Shredder, aeration duct, insulated chamber, carbon filter, controller and a six-probe sensor rail.

02 / Assembly

175 × 110 × 145 cm

Reinforced composite panels on a steel frame, 120–150 kg empty. Sited outdoors without a shelter.

03 / Loading

Waste goes in at the top

Leaves, grass, twigs, garden trimmings and food waste. Up to 150 kg per cycle through a removable lid.

04 / Shredding

Large pieces in, 10 mm out

Coarse rotors break down branches. Fine rotors below take everything to roughly 10 mm, which is what makes the rest of the cycle fast enough to be useful.

05 / Aeration

Air pushed up through the bed

A variable-speed fan feeds a perforated duct beneath the material, holding oxygen near 18 per cent. Spent air leaves through an activated carbon canister.

06 / Sensing

Six probes, continuously

Temperature, humidity, oxygen, pH, moisture and ammonia. The bed holds in the fifties for weeks and loses about two thirds of its mass.

07 / Output

Compost, not waste

Nutrient-rich material ready for landscaping, parks, nurseries and agriculture.

Configurations

Three kinds of waste. One platform.

What goes in decides the machine. The chamber, the sensor array and the control system are shared across all three — the shredder, the airflow and the materials around them are not.

Sited beside the kitchen it serves. Cooked and raw food, fruit and vegetable trimmings, coffee grounds and bakery waste go in at the end of service and never reach a bin room.

Engineering

Before it was a specification, it was a box on a bench.

The first working unit was designed and built at Bahrain Polytechnic — a printed enclosure, two geared drives, a sensor array and an ESP32 holding it together. It was built to prove the cycle closes: that material can be reduced, aerated, measured and weighed inside one sealed volume, and that the readings can leave the box.

The schematic

The whole system, on one page

Six measured channels, two driven axes, one fan, and a battery that lets the unit run detached from mains.

Every sensor lands on a named pin. This is the diagram the build above was wired from — the components you just looked at, and the lines between them.

What went into it

The prototype proves the architecture, not the production unit. The enclosure measures 233 mm square; the pH and oxygen channels appear on the schematic and in the bill of materials but are not fitted in the photographs above. Everything shown here was built and tested at Bahrain Polytechnic and took first place at Engineering Expo 2026.

Recognition

Verified by the people who would have to use it.

Two ministries, a cultural bureau, an engineering faculty and a national port have looked at this project and taken it further.

Receiving the 1st Place Award for Best Innovative Project at Engineering Expo 2026, recognising our innovation and commitment to sustainability. Award ceremony, Engineering Expo 2026, Kingdom of Bahrain — first place among more than 300 participating engineering projects.

Project and team certified by Prof. Christina Georgantopoulou, Dean of Engineering, on completion of the final-year engineering programme.

Recognised as a national model. Built to become a national system.

CompostEgo is designed and manufactured in Saudi Arabia. The ambition is a network of units reporting into one place, so a municipality, a port authority or a ministry can measure organic waste the way it already measures water and power — which is what Vision 2030 asks of the environmental sector, and what nobody can currently do.

Put one on your site and watch it work.

A pilot places a CompostEgo unit in a real operating environment — your waste, your staff, your conditions — so the case is made on your numbers rather than ours.

Duration and cost are set after the assessment, and depend on waste volume, location, configuration and scope. We'll be specific once we've seen the site.

We reply to every request. The introductory call is usually within a few days.
