Infrastructure & Engineering Group

Built On Engineering.
Driven By Innovation.

FEG is an infrastructure and engineering group delivering practical, technically-grounded solutions — from civil engineering and contract administration to the design and deployment of next-generation circular infrastructure platforms — for local authorities, governments and island states.

We bring together deep engineering expertise with adaptable, technology-led delivery models, combining hands-on project and contract administration with the design of bespoke, modular infrastructure platforms matched to each client's needs.

Civil Engineering & Contract Administration

Through FEG Consultants, we deliver and administer local infrastructure projects, applying rigorous technical oversight from design through construction.

Circular Infrastructure Solutions

Through FEG Island Infrastructure Group, we design and deploy the Circular Infrastructure Alliance Platform (CIAP), a flexible technology platform that transforms waste management for Small Island Developing States.

We leave value, not waste.

Resource Flow Visualisation

Two flow lines, every output a product.

MSW and biomass each pass through pre-treatment — metals and chemicals recovered before the burn — then incineration yields grid energy, heat for sand batteries and desalination, captured CO2, and ash transformed into aggregates and cementitious material.

MSW flow line

Landfill-diverted municipal solid waste

Recovered metals

Ferrous and non-ferrous recovered at pre-incineration sorting

Recovered plastics

Plastics separated at the same pre-incineration sorting stage as metals

Energy to grid

Direct electricity export from incineration

Sand batteries

Heat offtake stored as long-duration thermal energy

Fresh water

Heat-driven desalination, potable and industrial supply

Industrial salt

Recovered from desalination brine

Second-pass metals

MSW ash only — screened a second time after incineration to recover remaining valuable metals

Modified MSW ash

Post-burn processing of the screened ash

Phase 1 CO2 capture (mineralisation)

CO2 is locked in through mineralisation as the aggregate is formed

Aggregates / engineered fill

Modified MSW ash mineralised and pelletised into construction material

Stage 2 CO2 capture (natural weathering)

The formed aggregate keeps absorbing CO2 as it cures — earning carbon credits

Biomass flow line

Organic fraction with pre-treatment chemical recovery

Chemical extraction

The pre-treatment stage — valuable chemicals are extracted from the organic fraction before incineration

Recovered chemicals

The chemicals recovered at extraction, sold as a product stream

Energy to grid

Same energy streams as MSW during incineration

Sand batteries

Heat offtake into thermal storage

Fresh water & salt

Via heat-driven desalination

Biomass ash

Chemically different from MSW ash — no second metals screening is applied

Cementitious material

Modified biomass ash — sold separately, used in its own aggregates, or blended as feedstock into MSW aggregate production

CO2 capture — two stages

Phase 1 CO2 capture (mineralisation) as aggregate forms; stage 2 CO2 capture (natural weathering) as it cures

Future feedstocks

These streams do not require incineration. They are already inert or spent, so they enter directly at the mineralisation stage — a separate class of feedstock, assessed case by case and not part of current scope.

Mining fines

Fine tailings left over from ore processing, mineralised directly into aggregate without incineration.

Sewage sludge

Dried municipal sludge, stabilised and bound into construction material rather than landfilled.

Brown coal PFA

Pulverised fuel ash from lignite generation — already combusted, so it enters at the mineralisation stage.

Bauxite red mud

Highly alkaline alumina refinery residue, neutralised by CO2 mineralisation into usable fill.

Steel slag

Furnace slag with strong carbonation potential, converted into aggregate while locking in CO2.

CKD / CBD (cement)

Cement kiln and bypass dust, reused as a reactive binder feedstock instead of being wasted.

Deployment Circuits · Working Structure

Caribbean Deployment Circuits

Three working circuits group island states into shared service areas. Circuits A and B run on a standard municipal waste basis; Circuit C is assessed on biomass — rice husk ash — instead.

Circuit Map · Indicative

Selected Circuit

Circuit A — OECS North

Countries: Montserrat · St Kitts and Nevis · Dominica · Antigua and Barbuda
Feedstock: Municipal solid waste + tourism and construction streams
Assessment Basis: Standard MSW assessment basis
Status: Working structure — lead circuit

Note: circuit boundaries beyond A and B are not finalised. They depend on the outcome of the feasibility study, so this should be treated as the current working structure rather than locked geography.
