Discarded clothes: a new lease on life

re:newcell, a Swedish company, has developed and patented textile recycling technology. “Our process converts cellulose fibers from cotton and trees (rayon) into a pulp to produce new. The technology is unique and is based the pulp industry methods,” says Gunnar Henriksson, professor of wood chemistry and co-owner of re:newcell.

Microfungi replaces fishmeal

Zygomycetes are microfungi that decompose dead plant material. They grow well on sidestreams from forest and agricultural industry, providing a nutritious and environment-friendly biomass, suitable as fish feed.

Oil out of waste

Cassandra Oil's thermal reactors extract oil from waste containing hydrocarbons. Tires, plastic and oil-polluted water can be used as feedstock, with little need for sorting. This saves natural resources and contributes to the circular economy.

Geoengineering to offset climate change?

Even with zero emissions, we may deem it necessary to reduce the atmospheric carbon concentration. Solar radiation management techniques could be employed as a stopgap solution to offset a global temperature on the rise. Such deliberate acts of climate intervention are referred to as geoengineering.

The sun is cooling Väla Centre

The largest solar installment in Sweden is on the roof of the Väla Centre shopping center. The solar cells generate all the energy needed to provide cooling for the 180 shops – and 450 tonnes of emissions are saved annually.

Can we pull the carbon out of the air?

Negative emissions is one of the important tools mentioned in the Paris agreement. We can capture carbon from flue gases and deposit it in underground reservoirs, and growing biomass can do the sequestration. The technology is expensive and energy-intensive, but it is evolving.
