We have a track record in the execution of projects in the Renewables sector, primarily in the areas of biogas and materials recovery from solid waste. Project Assignments is also able to provide independent advice on the design, procurement and installation of solar photovoltaic (PV) facilities.



In the biogas space, we have executed contracts involving the generation and clean-up of gas originating from the treatment of high-organic strength wastewaters as well as the digestion of municipal sludges and other solid organic wastes. We have designed both high-rate and low-rate digestion systems, utilising both granular and flocculant sludge reactors.


We have expertise in the treatment of biogas, utilising biological scrubbers and activated carbon to remove moisture, siloxanes and hydrogen sulphides, as well as in membrane systems to upgrade the gas to pure methane and carbon dioxide. Utilisation of biogas in combined heat and power (CHP) engines is also part of our track record.


Solid waste and materials recovery

On the solid waste front, we have been the Engineer on projects involving the recovery of papers, plastics, ferrous and non-ferrous metals from municipal solid waste.


Solar PV installations

There are many pitfalls when trying to decide whether your site can benefit from solar PV, what features to include, what vendor selection criteria to apply and how to evaluate proposals on a technical and commercial basis. As we are a truly independent service provider, carrying no equipment agencies, we can offer an objective professional engineering service that includes:

  • Assessment of your energy needs, based on historical records and future plans
  • Compilation of a Request for Proposal, incorporating basic technical and commercial conditions to ensure like-for-like offers
  • Handling of all clarifications required to enable a full understanding of vendor proposals
  • Compilation of an Adjudication Report, making recommendations as to the optimum combination of technical and commercial features
  • Project management and construction supervision (if required) of the selected solar PV installer, to ensure that all expectations are met
