Millions of Tonnes of Biomass Get Burned Every Year. Most of It Shouldn't Be.

Agricultural residue, wood chips, and other biomass waste pile up faster than most operations know what to do with. Biomass carbonisation turns that pile into a carbon-rich product instead of a disposal problem. Let's start with a number: every harvest season, farms and mills generate tonnes of leftover material, straw, husks, stalks, and offcuts with nowhere useful to go. A fair amount of it ends up burnt in the open. Not stored. Not processed. Just gone, along with whatever value it might have held. That's the gap biomass carbonisation was built to close. The process On paper, it reads simply: take biomass, apply controlled heat, and cut off the oxygen, and you're left with a carbon-rich solid. In practice, industrial carbonisation is a far more deliberate process than "heat it and see". The feedstock matters. The temperature matters. How long the material stays in the reactor matters. And what you actually want out the other end matters most of all. Inside the ...

Calorific Value of Ethanol: HHV, LHV and Energy Content Explained

Ethanol is a growing part of transport fuel blends today. Its energy content matters to any engineer working with it. Calorific value is the number that shows how much heat ethanol can release during combustion. It shapes fuel consumption estimates, thermal performance checks and energy balances. Pure ethanol has a higher heating value of around 29.7 MJ/kg. Its lower heating value sits closer to 26.8–26.9 MJ/kg. That gap matters. Industrial combustion systems rarely recover all the heat locked in the water vapour that combustion produces. What Is the Calorific Value of Ethanol? Calorific value is simple at its core. It is the heat released when a fixed amount of fuel undergoes complete combustion under set conditions. Ethanol undergoes combustion through this reaction: C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O. But the exact heat released depends on one thing: what happens to the water formed. That is why ethanol carries two figures, not one – a higher heating value and a lower heating value. HHV and...
