STHS Consulting Ltd is an official partner of OMPECO Middle East, Africa, Asia and Pacific Islands (www.ompeco.me). I can be contacted at stephen@ompeco.me for matters concerning this order.

Our product, The Converter, is an innovative way to manage waste, transforming all forms of rubbish into a safe, dry, and reduced final product using a completely mechanical process that harnesses the principle of mechanical to thermal energy transformation.

The key benefits of OMPECO are:
- Zero Emissions: No pollutants or harmful substances released.
- Safe Output Material: Produces sterile, odourless, dust-free, non-fermenting, and vermin-free material.
- Significant Reduction: Up to 50% weight reduction and up to 80% volume reduction- Zero Landfill.
- Environmentally Friendly: No use of chemicals, combustion, microwaves, or pressure.

The Converter is a 100% sustainable, zero waste, zero emission solution that eliminates the need for waste separation. Simply load the machine, The Converter will remove any liquid, converting the waste into premium grade refused derived fuel (RDF) with high calorific value in only 30 minutes. The resulting RDF is a sterile, inert flock suitable for fuel or domestic disposal, eliminating odors, dust, and refrigeration needs while ensuring long-term storage stability. This can then be safely stored or even sold on for use in the circular economy (see attachment on medical waste)
