Every one of them buys fuel, converts it to heat, uses a fraction of it, and rejects the rest through stacks, condensers and cooling towers. Sidel CREN's waste heat recovery systems recover that rejected energy, store it, reuse it, and convert it — energy that's already paid for.
A 365-day heat-and-cooling machine: milk reception, chilling, pasteurisation, CIP, drying, cold storage, boilers, generators and effluent.
A thermal plant with a product attached — bagasse boilers, evaporation, batch pans, vacuum systems, spray ponds and condenser water.
Enormous value rejected through boiler and generator exhaust, condenser heat, cooling towers, blowdown and stack losses. Coal adds particulate.
The strongest long-term market — multiple high-grade and low-grade streams across furnaces, coke/sinter, EAF, rolling, quench and off-gas.
The fastest-growing electricity load in the country — cooling alone can be up to 80% of non-compute power draw, and liquid cooling is finally making that heat recoverable.
Ready-mix is thermally light, but precast and prestressed plants run curing chambers, boilers and batch-water cooling at nearly ten times the energy intensity per unit of product.
Concentrated solar thermal collectors direct heat straight into Novacab TESS, which discharges through an ORC turbine on demand — dispatchable power for essential community loads, no lithium-ion battery required.
The figures below are planning-level references drawn from real reference plants and engineering analysis. They are here to show the scale of the opportunity and the questions worth asking — not to quote your site. Every number becomes a real number only after metered baselines, a site thermal map, and third-party measurement. That discipline is the whole point of our approach.
Planning-basis figures, the waste-energy map, first-pilot approach and the exact data we'd ask for — on its own page for dairy, sugar mills, gas & coal power, steel & metals, data centers, concrete manufacturing, and the community microgrid. Pick a card above, or a menu link, to go straight there.
RPC removes the solid pollutants. SRU and TESS strip the Btus across an 800°F-to-122°F cascade and convert what qualifies into behind-the-meter electricity. What remains — CO₂ and water vapour — becomes the input to a greenhouse complex producing food year-round. More on the power generation page.
Regardless of sector, a Sidel CREN retrofit shifts the same five categories.
| Category | Existing infrastructure reduced in use | New infrastructure added |
|---|---|---|
| Thermal rejection | Cooling-tower duty cycles, spray ponds, condenser thermal load, plume, evaporation, makeup water, blowdown and chemical treatment. | TESS/SPCM modules, heat exchangers, recovery headers, piping, thermal controls, and measurement & verification. |
| Boilers & steam | Fuel firing rate, cycling, stack heat loss, blowdown burden, steam venting, hot-water dumping and manual steam balancing. | SRU flue-gas condenser and heat exchanger, condensate handling, hot-water or makeup-water preheat, and a TESS thermal buffer. |
| Cooling & chilling | Chiller and compressor runtime, peak electrical demand, refrigeration shocks, cold-storage swings and emergency utility intervention. | TESS cold and thermal storage, controls, demand-response logic and a critical-load backup strategy. |
| Emissions & solids | Visible particulate burden and incomplete capture pathways for coal, biomass, wood, waste and fuel oil streams. | RPC particulate capture, engineering-selected back-end emissions controls, ducting, instrumentation and compliant ash/by-product handling. |
| Power & resilience | Grid exposure, diesel backup dependency for controls and auxiliaries, and lost production during outage and restart events. | Behind-the-meter generation from heat above ~53–55 °C where viable, ORC/binary-cycle interface, controls and black-start support design. |
We would rather send you a data request than a brochure. This is the list that turns a conversation into a bankable project.

All claims relating to site savings, water reduction, output increase, emissions outcomes, payback, incentives and deployment economics are planning assumptions, analogues or prior-project references — unless and until they are validated for your specific facility through engineering, measurement, vendor quotation, financing documentation, legal review and final commercial agreements.
