Gully Waste Recycling Solutions

OPS offer a range of scalable, WRAP protocol compliant gully waste recycling and treatment solutions for energy efficient gully waste dewatering, gully waste recycling and fully recovered ‘end of waste’ disposal for both existing plant upgrades and new facilities.

At OPS we have 10 years of experience in gully waste recycling. Our modular solutions for both wet and dry gully waste treatment are designed to site conditions, reducing the gully waste recycling overhead by optimising throughput, minimising energy use and delivering the maximum end of waste, WRAP protocol compliant by-product for resale.

Minimising the gully waste recycling overhead


Gully waste tends to be much finer than road sweepings, containing less stone ad trash / organics. The materials tend to be dirtier with more fine material holding most of these contaminants.

An effective gully waste treatment & recycling plant also needs to consider effective gully waste dewatering and waste water treatment due to the build-up of oil in the water and carry over onto the sand.

The preferred technology for gully waste recycling is using a simple spilt dewatering deck with oversize dewatered on one side of the deck and sand dewatered on the other side of the fraction.

OPS also can introduce the AEV – our high efficiency adiabatic expansion valve scrubber – into the equation which will further clean the sand particles to secure the inert label under the WRAP protocol.

The water is treated using electrocoagulation which rips the oil out which is then floated off using a DAF. A gully waste treatment plant should be hugely water positive so effective treatment will also enable cheap water disposal.

Whether you are upgrading an existing plant or commissioning a new facility, OPS can offer a turnkey WRAP protocol compliant gully waste recycling solution, generating end of waste accredited bi-products from both wet and dry gully waste, monetising ‘gully waste recycling and disposal.


Like the oily sand treatment plant, the OPS Road Sweepings Recycling Plant is made up of our own proprietary technology, 3rd party technology when required and off the shelf items. We have the flexibility to meet the customer’s exact requirements.  We can upgrade a plant or to create a plant from bare earth.

Energy Efficiency = Reduced Wear.

Gully waste is not a hazardous waste code and in some cases, it is almost inert; therefore, to ensure an environmental benefit (rather than just ticking a legislative box) a recycling plant has to be energy efficient. OPS design our plants with the following features:


  • Zero ’90-degree’ elbows on pipes transporting sand and water
  • Zero ’90-degree’ elbows at the outlet of pumps
  • Recirculation pump controlled by flowmeters and a pressure sensor to reduce energy consumption
  • Accurate control of sludge flowrate to ensure smooth and efficient centrifuge operation
  • To strive to be water neutral by capturing, treating and reusing all the water which comes into a site

As engineering systems integrators, we combine cost efficient 'off the shelf' products with our high throughput proprietary processes. Integrated by best in class process control into a single solution individually engineered to site conditions, OPS deliver consistent performance, reliability and optimised life cycle costs.
