Marble
Marble is a climate tech venture studio. Our north star is to erase billions of tons from annual greenhouse gas emissions and create a thriving future.
We partner with scientists, engineers and operators to create new deep tech companies that solve hard climate problems — slash emissions, remove carbon from the atmosphere, and cool the planet — while reshaping multi-billion $ industries.
We're proud to be backed by leading climate investors across Europe and the US.
Wastewater treatment is among the world’s most critical infrastructure, especially for sewage at the municipal level, but also in industry and agriculture.
Wastewater treatment plants use 4% of the world’s electricity, and are responsible for more than 3% of global GHG emissions, especially methane, nitrous oxide and carbon dioxide.
However, it could be possible to recover more energy from wastewater than what is required for treatment, along with nutrients and other valuable products, while slashing potent emissions. Various carbon dioxide removal methods have also been proposed to leverage the unique characteristics of wastewater treatment plants.
Meanwhile, several approaches could help mitigate freshwater scarcity and health hazards, such as advanced water treatment, zero liquid discharge, decentralised modular plants, and novel processes tailored for industrial use.
The impact potential is vast, but the wastewater sector is notoriously difficult to enter. We are exploring transformative approaches to overcome these challenges, and turn wastewater treatment into a massive climate positive industry.
We aim to create a company which can maximise both the climate impact and economic value of wastewater treatment plants — at the largest scale possible.
