Biodiesel from waste

A group of Spanish developers working for a company called Ecofasa just announced a new biofuel made up from trash. This isn’t a biodiesel made from used frying oil; instead, it’s made from general urban waste which is treated by bacteria. The result of that bacteria? Fatty acids that can be used to produce standard biodiesel. According to the company’s CEO, the process is fully biologic, competes with no feedstock and is really sustainable. However, the process doesn’t yield that much actual fuel: just one liter of biodiesel from 10 kg of trash. The project is now in a development phase, but Ecofasa said that a commercially viable model could be ready in three to four years. Source

Words are beautiful

Agritecture- structures to grow things in

Farmbot- everyone to grow food, grow food for everyone. 

Polycrops- mix and match different crops, rare in conventional agriculture. This creates an advantage by providing “superior biological efficiency”. The diversity within the ecosystem allows for the growing of vegetation in conditions as close to nature as possible. Plants are allowed to work together, like nature had originally intended. Farmbot allows for this to be possible by being programmed to cater to different plants’ unique needs.

Permaculture- Is an approach to designing human settlements and agricultural systems that emulate ecologic relationships from wild nature. It is a land use and community building movement focused on harmonious and sustainable integration of human dwellings and food production within the broader context of the micro-climatic, hydrological and biological landscape. 

Ecotechnology: the design of human society with its natural environment for the benefit of both. It is engineering in the sense that it involves the design of this natural environment using quantitative approaches and basing our approaches on basic science. It is a technology with the primary tool being self-designing ecosystems.
