Waste Facility Design

A Leader in Waste Facility Design

Activities carried out at waste facilities include disposal, treatment, recycling and energy generation. They are a crucial part of ensuring we sustainably manage the wastes produced by households, commerce and industry. These facilities are varied and include mechanical, thermal, chemical and biological treatment of wastes, soil remediation plants and landfill disposal. Materials that cannot be recovered or recycled, including the residues from treatment facilities, are disposed of in a landfill. Ayesa has extensive experience providing complete design services for waste facilities or providing specialist inputs to larger development consortiums.

Our team of multidisciplinary experts has delivered the design and master planning of nationally significant waste management projects in the UK and MENA region, including the 18 million cubic metre capacity, triple landfill Sohar Industrial Waste Handling and Treatment Facility (IWHTF) in Oman and at multiple, extensive scale waste management facilities over 20 years for the two leading waste management operators in the UK.

We can also design the remediation works at former waste management facilities, including treatment plants where soil and water contamination has occurred and historical landfill sites.
