Shrimp Shells Transformed into Carbon-Negative Fuel, Food, and Construction Materials

Scientists at NTU in Singapore developed a process converting discarded shrimp shells into carbon-negative hydrogen fuel, aquaculture protein, and calcium carbonate. This lab-scale technology aims to reduce waste and offer cleaner alternatives to fossil-based energy and industrial materials, though commercial scaling faces efficiency and economic hurdles.

How Shrimp Shells Are Being Turned Into ‘Carbon Negative’ Fuel, Food and Construction Materials

Scientists in Singapore have developed a process to convert shrimp shells and other organic waste into hydrogen fuel, protein for aquaculture feed, and calcium carbonate for construction. The technology, developed at Nanyang Technological University, aims to be carbon-negative by removing more CO2 than it produces, offering a dual solution for waste reduction and cleaner energy.

Australia's Rubbish Removal Stinks: Councils Seek Organic Waste Solutions

Australian councils are tackling the growing problem of organic waste, which produces potent methane gas in landfills. While kerbside Fogo bins are being rolled out, community-led initiatives like Yimby Castlemaine offer alternative, localized solutions for composting and waste management.

Back biomethane to cut UK import dependence and support rural economies, says Chris Huhne

Chris Huhne responds to Nils Pratley's article on UK gas policy, arguing that biomethane represents a third overlooked option between expanding North Sea drilling and increasing LNG imports. He highlights that biomethane is domestic, low carbon, storable and dispatchable, citing the IEA's 2025 Renewables report and examples from Denmark (meeting 40% of gas demand from green gas) and France (20%+ annual growth since 2022). The letter argues the UK lacks political will to scale these alternatives.
