Tropical rainforest in Indonesia

Southerly countries are rich in genetic resources. The companies that exploit this natural treasure commercially are very often from the northern, developed world, however. The Nagoya Protocol was created in order to ensure fair use of genetic resources and appropriate compensation.  Read more

Payment via mobile, replacement parts made on a 3D-printer, error messages via NFC-tag – Eawag doctoral student Caroline Saul has found some remarkable innovations in companies that market container toilets in developing countries. She sees great potential in making such technologies more widely available. Read more

Ultrafiltration is one of the techniques currently used for disinfecting water – viruses and bacteria are reliably retained by a membrane with extremely small pores. For more than ten years, Eawag has successfully been carrying out research to determine how this method can function using the effect of gravity on water instead of high pressure, cleaning and chemicals. These new discoveries are being applied in increasing numbers of ways. In addition to decentralised drinking water purification, Eawag is now researching uses in areas such as greywater recycling and pre-treatment of seawater for desalination. Read more

This April, Sandec and its partners hosted two national workshops on small-scale sanitation – one in New Delhi, India and one in Kathmandu, Nepal. The aim of the workshops was to discuss the results of two years of field research with participants from government, utilities, academia, donors, the private sector and NGOs. Read more

Researchers of the Eawag department Sanitation, Water and Solid Waste for Development (Sandec) and ETH Zurich are developing a method to produce animal feed from biowaste products. This is one of 14 projects in the Engineering for Development programme funded by the Sawiris Foundation for Social Development over the past decade and entering its next 5-year cycle. Read more

Faced with polluted river water, rural communities or aid agencies often drill groundwater wells to obtain water supplies. But data collected systematically for the first time in the Amazon basin show that this “solution” can create new problems: the groundwater may contain elevated concentrations of arsenic, manganese and aluminium – up to 70 times over the recommended limit in the case of arsenic, and up to 15 times for manganese.

The earth’s water supply is changing because of global warming: the ratio of precipitation to evaporation is sinking, and additional arid zones may emerge. The speed at which this development is likely to take place has been analysed by an international team including Eawag researchers.  Read more

A research team from the Surface Waters Research and Management Department is investigating the earliest traces of human life in the tropical Pacific. In July 2017, the team undertook an expedition to Vanuatu in Melanesia. The researchers took sediment cores from the lakes and marshes on seven islands in order to test these for indications of the earliest human activities. Read more

The EPFL has launched a new Massive Open Online Course (MOOC) in collaboration with Eawag’s Sandec department and the International Committee of the Red Cross (ICRC). The course is designed to shed light on the important role played by Public Health Engineers at times of humanitarian crisis, and how health risks can be mitigated. Read more
