Carbon Zero

MIT spinout Boston Metal has powered up its electricity driven steel production reactor and made over a ton of metal in a crucial step toward commercializing its process. With clean electricity, the process could make steel with zero CO2 emissions.

A new material tackles the carbon problem of concrete production and usage by employing a pretty unusual workforce: cyanobacteria. The bio-cement these micro-organisms help to produce harnesses a process that's existed in nature for 3.5 billion years.

The industrial sector is responsible for about 25% of global CO2 emissions – or about 9.3 billion metric tonnes per year and growing. But a team at the University of Leeds says we don't need to wait for magical new tech to clean most of it up.

Sublime Cement says it's ready to start scaling on the "world's cleanest cement," which meets industry performance standards relying on room-temperature electrolyzers in place of fossil-fueled furnaces, using a variety of zero-carbon input materials.

Architect Ivana Steiner has created a zero-waste kitchen designed to take the effort out of living a zero-waste lifestyle. Inspired after visiting several "unpacked" shops in Vienna, she created the perfect low-fuss waste-free kitchen.

Volvo's performance brand Polestar has revealed plans for a forthcoming model that will be entirely carbon neutral, which would involve a dramatic rethink of the company's entire production process to avoid the "cop-out" of carbon offsetting.

Practice Architecture has built a family residence using prefabricated panels made with hemp. The result is a sustainable three bedroom home dubbed Flat House, which boasts a flat-pack design using materials grown on the 20-acre property.

Australian developer Grocon is planning to be among the first to build the first carbon neutral office building.

The sleek modern capital of the United Arab Emirates, Abu Dhabi, will soon be home to what is planned as the world’s first zero carbon, zero waste city.
