Again is a Danish company based in Copenhagen that offers technologies that use fermentation to decarbonize industrial operations, turning CO2 emissions into useful products. Combining captured CO2 and hydrogen obtained from biological feedstock, the company is able to produce ”green” chemicals.

On its website, Again explains the current situation and where we need to be heading in order to keep the planet under control, emissions-wise. Thus, by 2050, we need to remove about 59 gigatons of greenhouse gas emissions, so that we prevent the global warming phenomenon from getting worse.

All industries, as per Again's calculations, contribute to the problem with 12 gigatons of greenhouse gas emissions every year, due to their reliance on carbon-rich sources. Out of those, 3 gigatons come exclusively from the production of chemicals, which the company can address. By using these emissions to produce more planet-friendly chemicals and derived products, the company can reduce as much as 25% of the industry's carbon output.

Using a bioreactor, Again captures a lot of carbon emissions, which are then turned into CO2-negative chemicals using fermentation.

The resulted chemicals are purified to ensure optimal quality, so they can act as drop-in replacements. The final product is being sold, as per the company, at competitive prices.

Again's already operates a pilot plant in Copenhagen, which is able to convert as much as a ton worth of CO2 into useful chemicals, one of the products being acetate, useful for companies that work with adhesives or plastics.

Extracting lithium with a lower impact on the planet

Lithium extraction can have a significant impact on the environment, which is why many companies in this sector are seeking sustainable alternatives. International Battery Metals (IBAT) is one of them and it recently launched a direct extraction solution for lithium, which could help lower the environmental damages regular lithium extraction does.

The company's experts cite the fast buildout of the facilities as being one of the advantages. The other is a 95% recovery rate and 98% recycling of the water used for the extraction process. All in all, these solutions can help EV makers produce batteries faster and cheaper.

IBAT's technology extracts the lithium from brine using water and then reinjects the brine into the ground, resulting in a minimal environmental impact. At the same time, the lithium-extraction facilities are modular, meaning that they can be quickly implemented anywhere and disassembled when the extraction process is done.

Furthermore, the company makes use of renewable sources, such as solar power, to ensure that it generates as little greenhouse gas emissions as possible.

Reusing steam to make energy

Reusing existing renewable resources to generate energy is one of the goals of the power industry. NLine Energy is one of the companies that offers a technology capable of converting wasted energy from steam distribution systems from boilers at commercial and industrial sites in renewable power. The company's turbines generate electricity with an efficiency of over 80%, leading to important greenhouse gas reductions and energy cost reductions.

The system is fully automated using an intuitive interface and fits in most places, company experts say, due to its reduced size.

Currently, 9 turbines are being used, each with a 2-4 year return of investment rate, lowering the emissions and the costs associated with things like heating and electricity in universities, hospitals and lumber posts.
