AquaGreen, founded in 2014, is a Danish engineering company that has developed an innovative technology for treating wet biomass, particularly sewage sludge. The company's patented HECLA technology integrates steam drying and pyrolysis to convert bio-waste into valuable resources. This process dries and pyrolyzes sewage sludge at 650¬∞C without the need for auxiliary fuel, using only the calories from the sludge itself. The technology significantly reduces greenhouse gas emissions by approximately 80% compared to conventional sewage sludge disposal methods.
AquaGreen's HECLA 1,000 plant can process 1,000 metric tons of dry matter annually, reducing greenhouse gas emissions by 1,800 tons of CO2 equivalent, producing 2,000 MWh of sustainable energy, and storing 500 tons of carbon in biochar. The resulting biochar is odorless and contains 5-6% plant-accessible phosphorus, making it valuable for soil improvement and fertilization. The process also eliminates harmful pollutants such as microplastics, medical residues, PFAS, and PAH while preserving essential nutrients like phosphorus.
The company's technology offers a cost-effective and environmentally efficient solution for handling wet bio-waste, presenting a sustainable alternative to traditional sewage sludge management methods. AquaGreen's system is self-sufficient and circular, as the gases produced during pyrolysis fuel both the steam drying and pyrolysis processes. The excess steam, condensed into hot water, can be used for district heating grids and other applications.
Key customers and partnerships
AquaGreen has successfully installed its HECLA plants in Denmark, specifically in Zealand and Funen. The company has also expanded its operations to Sweden and South Africa. In July 2023, AquaGreen secured a tender to supply installations in Malaysia and Borneo. The company was also working on an offer for 11 plants in Saudi Arabia and exploring opportunities in China and Australia.
One of AquaGreen's key customers is Odsherred Forsyning in Denmark, where the world's first integrated steam drying and pyrolysis plant was implemented. This installation has enabled Odsherred Forsyning to transform sewage sludge from 50,000 citizens from an annual expense into a sellable product.

Molekule is a science and technology company specializing in air purifiers, founded in 2014 by Dr. Yogi Goswami and his children Dilip Goswami and Jaya Rao. The company's air purifiers utilize patented Photo Electrochemical Oxidation (PECO) technology, which aims to destroy pollutants at a molecular level rather than just trapping them like traditional HEPA filters. Molekule's flagship products include the Air Pro, designed for spaces up to 1,000 square feet, and the more compact Air Mini for rooms up to 250 square feet.
The PECO technology employs a UV-C light filter and free radicals to break down pollutants including volatile organic compounds (VOCs), bacteria, mold, viruses, and allergens. Molekule claims their technology can capture particles 1,000 times smaller than what HEPA filters trap. In testing, Molekule air purifiers have shown the ability to reduce common bacteria by over 99.99% and capture 90% of airborne particles as small as 0.3 microns in a 150 square foot room within an hour. The devices are certified by the California Air Resources Board (CARB) for low ozone emissions.
Molekule air purifiers feature a cylindrical design with a 360-degree air intake at the bottom and an outlet on top. The devices can be controlled via a smartphone app that allows users to check filter status and view air quality data. Filters typically need replacement every six months. While praised for their sleek aesthetics and innovative technology, Molekule air purifiers have faced criticism for their high price points relative to performance compared to some traditional HEPA purifiers.
