What used to be a run-down district in Valladolid, Spain has now become a model of sustainability.

In the suburbs of Valladolid, a city in central Spain, a district is at the forefront of Europe's energy transition. With its 19 residential buildings and a single tower block, surrounded by a small park, it was built in the 1960s for employees of the car manufacturer FASA-Renault, which gave its name to the neighbourhood. The factory workers have long since moved on, and this middle-class district is now home to many retired people.

The RIKEN Center for Sustainable Resource Science in Japan has found that torrefied biomass retained more water, an important quality for good soil.

In the study, the researchers used soil from Botswana, an arid region in Africa.  When biomass was introduced to the poor soil, water retention was increased and the plants grown had thicker stems, longer roots, and weighed more than those grown in untreated soil.

"SHARCs” and “Piranhas” eat heat from raw sewage and return it for use in buildings.

THEY MAY SOUND scary, but for the environmentally conscious and owners of multifamily buildings, International Wastewater Systems’ heat-seeking SHARCs and Piranhas are harbingers of a new energy source for buildings. These waste to energy products can conduct simple and direct heat exchange from untreated wastewater to provide energy-saving, cost-effective solutions for heating, cooling and hot water.
