Organic Waste:
Deeper Benefits
Organic waste is defined as biodegradable waste
with the potential to be composted or digested.
This stream is currently disposed in landfills mixed
with other household waste streams. be’ah finalized

Recover - Bright Solutions
for Energy Recovery
The proposed Waste to Energy (WTE) Plant at Barka
will divert 3,840 tonnes of MSW every day, producing
a net 137 MW/day of electricity, which will be
connected to the main grid. The project concept was
promoted to major stakeholders by demonstrating
its sustainability and impact on a national level -
from reducing environmental emissions, saving
landfill spaces, reduction of dependency on non-
renewable resources and attraction of foreign
direct funds to generation of employment.
Both be’ah and The Oman Power and Water
Procurement Company (OPWP) conducted feasibility
and techno-economic studies for developing the
WTE plant in Barka highlighting the concept design
and key operating parameters to be considered.

Another WTE initiative was studied with PDO, to

PDO and be’ah collaborated and finalized the
feasibility study which outlines multiple scenarios
for utilizing power and steam recovered from
incinerating approximately 960,000 tonnes of waste
per annum. This project will help PDO meet its
requirement for high-pressure steam to be used for
