Environmental benefits often come through hi-tech solutions and excellence, but they can also come from surprisingly simple techniques.

The Sundsvall hospital is cooled with an energy saving of 95% compared to traditional systems. Solvatten purifies water in developing countries, providing both environmental, health and economic benefits. Longopacs seemingly simple garbage bags generate 11 times less carbon emissions.
These three examples show that they are low-tech, but have great environmental benefits.
