AI from human neurons and the latest technologies for removing CO₂ from the atmosphere

The Swiss start-up FinalSpark has already tested 10 million living neurons during research on building thinking machines from neurons taken from human skin. The company wants to change conventional methods of creating artificial intelligence models. Instead of relying on digital processors, it believes it is worth focusing on biological ones that consume much less energy. The Swiss train neurons use electricity to process information in the same way as the human brain.

American start-up Graphyte has found a cheap way to remove carbon dioxide from the air. The company collects, dries and condenses unused CO₂-containing biomass into brick-like blocks, then covers them with an environmentally safe, impermeable coating. The blocks can then be buried underground for hundreds of years. Graphyte says the solution allows CO₂ storage for approximately $100 for 1 tonne. Meanwhile, the start-up Heirloom Carbon Technologies has just opened its first plant in the USA to remove CO₂ from the atmosphere in California. It is intended to capture 1,000 tons of carbon dioxide per year, and the company’s goal is to remove 1 billion tons of CO₂ from the atmosphere by 2035.

The world’s largest plastic sorting plant was launched in Motala, Sweden. Sorting up to 200,000 tons of packaging per year (40 tons of mixed waste per hour), it can accept all plastic packaging waste collected from all Swedish households. The plant, called “Site Zero”, can separate up to 12 types of plastic and recycle 95% of the packaging.
