How Gasification Turns Waste Into Energy

Published

on



Turning waste into energy has usually meant incineration – that is, burning our trash. But this method has major environmental drawbacks. Gasification could be a better alternative. It’s an old technology that proponents hope to repurpose as a cleaner and more economical waste-to-energy solution, and now a number of companies in this space say they’re on the verge of commercialization and expansion.

We produce over 2 billion tons of waste per year, a number that’s expected to grow by 70% by 2050. We’ve long sought ways to turn all this waste into energy, but this has usually meant incineration – that is, burning our trash – a method that many environmentalists say is far too polluting.

A better solution may lie in gasification, an old technology that advocates are trying to repurpose as a way to deal with our waste. Gasification companies don’t burn trash, instead they turn into a synthetic gas, in a process they say is both economical and eco-friendly.

This synthetic gas can then be converted into a wide variety of end products like electricity, diesel fuel, hydrogen fuel, or ethanol, depending on whats most valuable in any given market.

While in the past, gasification companies have struggled to scale-up and meet their energy production targets, now companies like Sierra Energy, Enerkem and Plasco say they’re ready to commercialize and expand.

AI’s Next Race: Cost, Control, and Compute

Published

on

By



The AI race is shifting from who has the biggest model to who can run, control and deploy AI most effectively.

Perplexity CEO Aravind Srinivas joins to discuss the company’s new orchestrator model, why he’s building on open-source Chinese AI, and his argument that “token value per watt” may decide the next phase of competition.

Then, Benchmark general partner Peter Fenton and Ollama CEO Jeff Morgan discuss the rise of open models, why enterprises are increasingly running models they can download and control, and what Ollama’s growth says about where the AI ecosystem is heading.

Together, the conversations get at one big question: in AI’s next race, will the winners be defined less by model access and more by cost, control and compute?
