Dutch biotechnology firm Ingrepro plans to harness waste from sewers, farms and industry to produce biofuel and algae, which it hopes will eventually power airplanes, its chief executive said on Thursday. This is an indeed an excellent effort to produce energy from waste.
Ingrepro plans four initial projects in the Netherlands, and is set to start the first in September which aims to supply 20 percent of a city's energy needs with bi gas made from sewage waste while using the leftover nutrients for algae production.
"A lot of waste waters have a lot of nutrients, and people don't know what to do with them -- so why not grow the algae in the waste," Carel Callenbach told in an interview.
"The waste of biomethane (biogas) plants has very rich nutrients left over. At the moment they just pump it to the river or throw it away -- but we say next to these biomethane plants you need to build algal ponds to grow biomass."
s will use the waste from the potato industry, a food composting company and a ge farm to produce energy from biogas and cultivate algae.See more
