Qualification & testing
New fuel pathways face long approval and engine-testing timelines and limited early-stage validation capacity. Shared testing and grouped pathway cohorts can shorten the road to certification.
Solutions
WTP Carin consolidates integrated renewable-energy businesses — EV charging, EV drones, grid services, anaerobic digestion and waste-plastic conversion to renewable fuels — each engineered to stand on its own commercially while moving Ireland and Europe toward a circular, low-carbon economy.
01 — Anaerobic Digestion
A single digester is designed to process 250 tonnes of waste a day, breaking it down in sealed tanks to recover biogas, clean water and metals. Rather than depending on grants alone, each plant is built to earn from several revenue streams at once.
Plant economics
02 — EV Charging Infrastructure
We develop scalable charging networks that tackle range anxiety on long-distance routes across Ireland and Europe. A first deployment of 37–38 chargers is delivered through an Ireland–Poland joint venture, with projected returns in the opening months of operation.

03 — Waste-Plastic to Renewable Fuels
European restrictions on high-end plastic packaging have created urgent demand for alternatives. We are developing conversion routes that turn waste plastics into renewable fuels and low-carbon products — keeping their energy value in use rather than in landfill. The effort is supported by private investment partners in Canada and feeds directly into our wider energy and fuels work.

04 — Energy & Supply Chain
This is where the economics come together. Generating clean power at just 2–4¢ per kWh and clean gas benchmarked at roughly $40–50 per MCF, each plant earns a healthy spread between what energy costs to produce and what it is worth on the market. Crucially, that revenue is stacked across several streams at once — power and gas sales, tipping fees for accepting waste, recovered water and metals, and EV charging — so returns never hinge on any single price, and cash flow holds steady through market swings.
Disciplined procurement protects those margins. By securing around half of total equipment value up front and prioritising long-lead items such as compressors and rotating equipment, we shield projects from cost inflation and supply-chain delay — keeping construction on schedule and bringing revenue forward. Lower cost in, more value out, and fewer surprises in between: that combination is what turns a waste problem into a durable, self-funding business.
Energy & procurement
05 — Synthetic Fuel & Circular Economy
The pillars connect into a single circular system. Recovered energy and feedstocks feed into synthetic and low-carbon fuels — developed with our fuels partner Synthec Fuels — while materials, water and metals are kept in circulation rather than sent to landfill. It is a true waste-to-product model: every output finds a use, and nothing is wasted twice.
The loop
06 — Grid Services & Virtual Power Plant
Beyond generating clean power, our cloud platform links stationary batteries and EV batteries into a single virtual power plant (VPP) — supplying grid-balancing and primary frequency containment reserve (FCR) services to the utility. As more renewables raise grid volatility, this stored, dispatchable capacity helps regulate voltage and frequency in real time and smooths the daily demand ramp, without building fossil-fuelled “peaker” plants.
Grid services
07 — Vehicle Electrification
We help government and private operators move combustion fleets — cars, vans, buses, light and heavy trucks — to battery-electric over time. Our “fleet as a service” programme covers acquisition, leasing, maintenance and vehicle-to-grid services, supported by leased EVSE chargers procured, installed and maintained at depots, worksites and public sites. Those vehicle batteries then feed back into the same virtual power plant.
Electrification
08 — EV Drones
Battery-electric drones extend our renewable energy beyond the road. We are developing EV drone services and the charging infrastructure behind them — low-emission aerial platforms for logistics, site inspection, infrastructure monitoring and environmental surveying, charged from the same clean power our plants and networks generate.

Performance, cost and revenue figures on this page are design targets and projections based on current plans — not guarantees of future results. Actual outcomes depend on feedstock, site and market conditions.
The conversion process
Depending on the feedstock, our systems route each fraction of the waste stream to its highest-value use — from organics digested into energy and fertiliser, to plastics, tyres, glass and metals recovered as fuels and saleable commodities.
Processed through anaerobic digestion into methane, CO₂, fertiliser and water.
Converted into crude oil and refined fuel oils.
Processed into liquid fuels, carbon black and recyclable steel by-products.
Separated and gasified, or sold into existing recycling.
Crushed for abrasive blasting today — and, when selectively sorted, recoverable as furnace-ready cullet for new glass or as aggregate for concrete, road base and filtration.
Recovered and sold into existing markets.
Glass recovery
Crushed glass already works as a silica-free abrasive for paint and rust removal. But once it is colour- and contaminant-sorted, the same stream unlocks much higher-value routes — from furnace-ready cullet that goes back into new glass, to construction aggregate, filtration media and finished surfaces. The cleaner the sort, the broader the market.
In float-glass manufacturing (the Pilkington process), recycled cullet typically makes up 15–20% of the raw batch — cutting virgin raw material and furnace energy, where every 10% increase in cullet lowers furnace energy by about 2.5–3%. Optical and chemical consistency requirements mean post-consumer cullet must be carefully managed, which is exactly where selective sorting adds value.

Water treatment & marine services
Water treatment is built into our digesters: a closed-loop system that typically runs on municipal non-potable wastewater and treats all types of Contaminants of Emerging Concern (CECs) to discharge clean water under the strictest standards. Our patented Integrated Wastewater Diversion System (IWDS) extends this to greywater and bilge water — a marine service for cruise and cargo vessels calling at Irish ports such as the Port of Cork — turning organic sewage into green energy and soil amendments.

Sustainable aviation fuel
Aviation can't simply plug in. For long-haul flight, sustainable aviation fuel (SAF) — made from waste, biomass and recovered energy rather than fossil crude — is the most credible route to lower emissions this decade. Demand is climbing under mandates such as ReFuelEU Aviation, but supply is still scarce.
Where we fit
SAF and our synthetic-fuel work share the same starting point: sustainable feedstock and clean, recovered energy. Through our digesters, waste-plastic conversion and fuel partners, WTP Carin is positioned to supply inputs that SAF pathways depend on — inside a circular, low-carbon-intensity model rather than competing with food or land. Beyond production, the WTP Carin team provides the expertise to support the marketing and storage of synthetic aviation fuels into Europe — helping producers reach the market that mandates are creating.
SAF at a glance
The challenge
Scaling SAF is a shared, cross-industry effort. These are the barriers the whole value chain — producers, financiers and policymakers — is working to clear.
New fuel pathways face long approval and engine-testing timelines and limited early-stage validation capacity. Shared testing and grouped pathway cohorts can shorten the road to certification.
Sustainable biomass is contested across road, marine, chemicals and power, while e-fuels need cheap renewable hydrogen. Directing waste-based feedstock to its highest climate value matters most.
Uncertain revenues and binary pass/fail rules deter investment. Carbon-intensity-based incentives, guarantees, aggregation and book-and-claim can de-risk projects and unlock funding.
Linear vs circular
The old model treats resources as disposable. Ours keeps them moving — the difference between a dead end and a loop.
Resources are extracted, used once and thrown away. Value, energy and materials are lost for good — and the cost lands on the environment.
Energy and materials are recovered, used and returned to the cycle. Less landfill, fewer emissions, and new revenue from what used to be a cost.
