What if there was a way to produce energy, whilst reducing waste from wood & agricultural industries? Introducing Estonia-based Bioreactor, which is building a bioreactor - clue's in the name - that acts as a miniature power plant for domestic use. The startup utilizes the process of “biomass gasification” to convert biowaste into heat & electricity. Otherwise said, “the synthesis gases arising from breaking down organic matter are used as fuel for a combustion engine to generate electricity”. In addition, the bioreactor also produces heat, which can be used for space & water heating. Both things combined give the bioreactor a thermodynamic efficiency of up to 95%, able to produce 1kW of electricity & 3kW...

Founded by Karol Kaniuk in 2011 & joined by (his brother) Lech Kaniuk (CEO) in 2018, Sweden & Poland-based SunRoof builds “whole roof surface” solar panels/ tiles (not unlike Tesla’s famed "Solar Roof"). SunRoof claims its “solar tiles” are cheaper, as they use fewer materials/ resources (vs. traditional PV panels), with an aesthetic design that pleases customers. The SunRoof system also comes with energy storage & a digital platform where SunRoof customers can track every stage of their roof’s construction (from design to build to delivery) & once operational, a complete oversight of their energy production & consumption via an app. The new funding extension (fresh off the heel of a first closing in 2022)...
