Climate-neutral wastewater treatment plants thanks to patented real-time analytics - 08/11/2023

Using AI to reduce greenhouse gases in wastewater companies

The wastewater industry is responsible for global greenhouse gas emissions equivalent to those of global aviation. The start-up Variolytics has found a way to significantly reduce greenhouse gases in wastewater treatment plants using real-time analytics. The patented sensor technology and AI-supported process optimisation offer multiple benefits: in addition to reducing nitrous oxide, the system helps to reduce energy costs and resources.

Wasser 3.0: #detect|remove|reuse - 31/10/2023

How to sustainably remove and recycle microplastics from water

We all pollute our water with things we use in our everyday lives. In the process, microplastics and micropollutants accumulate in sometimes significant quantities and are difficult to remove. This has increasingly devastating consequences for our health and the environment. Wasser 3.0, a non-profit start-up from Karlsruhe, has declared war on this problem by developing a customisable process to detect, remove and even recycle these pollutants.

PeePower™ – energy from urine

The objective of the PeePower™ BUGA 2023 collaborative research project is to produce green hydrogen and platform chemicals from wastewater. This fits in nicely with BUGA 2023’s (German National Garden Show) four major themes, namely, climate, energy, environment and food security.

Wastewater treatment plants as biorefineries: the RoKKa project

RoKKa, a joint project coordinated by the Fraunhofer IGB, is testing methods for recovering raw materials such as phosphorus and nitrogen compounds to produce fertiliser from municipal and industrial wastewater in a climate-neutral way. These new methods are being investigated under real conditions at wastewater treatment plants in the Ulm area with a view to developing them into sustainable biorefineries.

KoalAplan: municipal wastewater as a source of recyclable materials

Our wastewater not only contains dirt and excretions, but is also rich in carbon, nitrogen and phosphorus, which can be recovered. A sewage plant can thus become a source of raw materials. In the KoalAplan project, a new type of biorefinery will be used to convert the carbon recovered from wastewater into sustainable products.

The Ministry of the Environment, Climate Protection and the Energy Sector is funding the KoalAplan project, which extends the functional scope of a wastewater treatment plant. The project, based in the Stuttgart district of Büsnau, aims at recovering raw materials from wastewater and is therefore making a positive contribution to climate neutrality, as the products obtained replace fossil raw materials and energy-intensive processes.

The Ministry for the Environment, Climate Protection and the Energy Sector is funding the new research project RoKKa which is used to prove the viability of recovering raw materials from wastewater. This adds a crucial function to the scope of a conventional sewage treatment plant. Together with the operators of the sewage treatment plants in Erbach and Neu-Ulm, the project partners demonstrate the positive contribution towards climate protection…

Phosphorus recovery from sewage sludge - 21/10/2020

Bacteria help to recycle phosphorus

Biotechnology for the bioeconomy: in something known as the P-bac process, sulphur bacteria extract phosphorus from sewage sludge ash. Phosphorus is one of the key building blocks of life and an essential nutrient for plant growth. When there is not enough phosphorus in the soil, farmers apply it via organic or mineral fertilisers.

Scientists to combat antibiotic-resistant bacteria in wastewater

In Germany, around 1,500 tonnes of antibiotics per year are administered to humans and animals. As a result, more and more bacteria are developing resistance to common antibiotics. As part of HyReKA, a cooperative project funded by the BMBF, scientists led by Professor Thomas Schwartz from the KIT are investigating how antibiotic-resistant pathogens spread and how they can be prevented from doing so.
