​ Producing ethylene from food waste without greenhouse gas emissions

 

A research team at the Korea Institute of Science and Technology (KIST) have developed a process technology and catalyst for removing hydrogen sulphide from the process of ethylene production from methane in biogas.  This biogas contains a significant amount  ofhydrogen sulfide, which interferes with the catalytic reaction in ethylene production. The new technology improves the ethylene production by oxidizing and removing hydrogen sulfide during the production process. This creates a biogas that burns cleaner with less pollution.

Greenwashing for Beginners: How to Spot an Eco-Con

  Greenwashing for Beginners: How to Spot an Eco-Con ( Or: Just Because It’s Green Doesn’t Mean It’s Clean ) Ever bought a product that had leaves on the label, a name like “Eco-Fresh Ultra Clean”, and a picture of the Earth… only to discover it’s wrapped in five layers of plastic and was shipped from the other side of the world? Congratulations. You’ve been greenwashed. Let’s dive into what greenwashing is, how to spot it, and how to avoid falling for it — even when it’s wearing a hemp T-shirt and whispering about carbon offsets. 💚 What Is Greenwashing? Greenwashing is when a company or product pretends to be more environmentally friendly than it really is — using marketing spin, misleading labels, and vague claims to make you feel good about buying something that’s… well, not all that green. It’s like putting a solar panel on a diesel truck and calling it “eco-aware.” 🧼 Common Greenwashing Tactics to Watch For 1. Vague Claims Words like: Eco-friendly Susta...

How My Heat Pump Became the Warm-Hearted Hero of Our Home

  Going Green: How My Heat Pump Became the Warm-Hearted Hero of Our Home ( Spoiler: It’s not just warm — it’s clever too. ) We used to rely on fire, gas, and the occasional desperate kettle-on-the-feet moment to warm the house. But now? Our warmth comes from thin air. Literally. Let me introduce the unsung champion of our eco-home : the air source heat pump . It hums quietly in the background, extracting heat from the outside air like some sort of eco-magician. And when paired with a chunky battery and a roof full of solar panels , it becomes a full-blown renewable romance. ☀️ The Sun’s Out, the Battery’s In We’ve installed 26 solar panels across three roof arrays , soaking up sunlight like a lizard on holiday. But sunshine is only half the story — the real magic is what we do with it. Enter our 50kWh battery system — a beast of a power pack that stores all that solar goodness and dishes it out as needed. It powers everything: the lights, the oven, the computers, and yes —...

  Battery Bling: Our 50kW Beast and Why It’s Not Just for Show ( Or: How We Power Our Lives, Our Work, and Our Tea Kettle Without Fossil Fuels ) Most people look at our battery bank and think we’ve gone full Bond villain. Rows of silent, blinking units. Three powerful inverters. Enough capacity to power a small festival. And they’re not wrong — except we’re using it for teaching, editing, music, and toast . Welcome to our all-electric, solar-powered, home-working, content-creating, music-making household . Where everything runs on electrons — and every watt counts. 💻 Why We Need Serious Battery Power We all work from home , which sounds quaint until you do the maths: One computer per person ? ✅ A server for video storage and backup? ✅ Video editing suite ? ✅ Multi-camera film studio with lights, mics, and a switcher? ✅ Synthesisers, Wersi organ, speakers and music production hardware? ✅ Electric cooker, oven, kettle, toaster ? Naturally. Charging the ...
