Scarcity of clean water is one of the most serious global challenges. In its
spearhead programme, VTT Technical Research Centre of Finland developed
energy-efficient methods for reuse of water in industrial processes and means
for recovering valuable minerals and materials from waste for recycling.
Rapid
tools were also developed for identification of environmental pollutants.
When water and wastewater systems are developed in a comprehensive manner, it
is possible to recover valuable metals and other materials and secure
availability of clean water.
Cleaning and treatment processes can also be
linked to energy production, and the processes and urban structures designed
in such a manner that wastewater treatment does not consume energy or cause
extra costs.
