500°C and potassium Methods

Sewage sludge produced during waste water purification contains not only biomass and pollutants but also precipitated phosphorus. By law, starting in 2026 this important component of fertilisers must be recovered, making Switzerland less dependent on phosphorus imports. In this context, HLS researchers are using pyrolysis to turn sewage sludge directly into fertiliser. This oxygen-free thermal process produces high-quality fertilisers, can easily be integrated into existing sewage treatment plants and will shortly begin a pilot phase.

A water filter for emergencies

Clean drinking water is a luxury. In many parts of the world water is polluted and full of harmful bacteria; the problem is particularly acute during humanitarian crises, such as in refugee camps. A simple short-term solution is a domestic water filter. There are many different types on the market, but their quality varies widely, so HLS researchers tested filters in three disaster areas. Working with the local population, they have made suggestions for product improvements.

Bacterial super-resistance decoded

Scientists and politicians agree: antibiotic-resistant bacteria are a major challenge for medicine, both now and in the future. The World Health Organization estimates that by 2050 more people will die as a result of infection by multi-resistant bacteria than from cancer. A team of researchers at the HLS have shed light on a particularly alarming mechanism by which bacteria not only survive antibiotics but even use them as nutrition.

Tailor-made membranes

Economic efficiency and environmental protection are often perceived as conflicting goals. Nevertheless, research shows that they can be combined if scarce resources are used efficiently or if raw materials are recovered. In the case of phosphorus, researchers at the HLS are already on the way to achieving this with the help of a multi-layer membrane that can be customised for specific objectives. In laboratory tests they have recovered 90 per cent of the phosphorus from acid waste solutions. The new technology will be used to extract phosphorus from sewage sludge.

Using bacteria against crude oil spills

Crude oil spills are one of the greatest risks to the industrialised world. Oil spills in the sea are not only difficult to contain but also highly resistant to natural decomposition. HLS researchers have taken up the fight. As part of the EU Kill Spill project, they are working with more than 30 partners from science and industry, developing biotechnology techniques to clean up oil-polluted waters.
