[1] One of the materials that demand the most amount of energy during producing, transport and construction. The amount of CO2 emitted by the cement industry is nearly 900 kg of CO2 for every 1000 kg of cement produced.
Nowadays plenty of experiments have been carried out to mix in different organic binding materials. The aims of doing this is to reduce the amount of cement needed in concrete structures and to make it lighter or stronger so it can be designed differently and cheaper. Some examples are horse hair, hemp fibres, old and shredded card board and paper, old crushed glass.
There are some companies that market concrete building blocks under different trademarks like: Glasscrete Hempcrete[2][3] Poly-Tuff-crete
