COMPOSTING ORGANIC WASTE<br />

Following the success of NorteShopping’s segregation of waste organic matter, <strong>Sonae</strong> Sierra decided to extend<br />

this project to other centres in Portugal, namely Arrábida Shopping, MaiaShopping and CascaiShopping in the<br />

last quarter of 2005. In January 2006, the facilities were installed at GaiaShopping.<br />

Each project starts with an analysis of the types of waste being produced, which lend themselves to composting.<br />

Then, special containers are distributed to tenants, who segregate organic waste before delivering it to the<br />

composting station.<br />

With this initiative, <strong>Sonae</strong> Sierra has recovered about 620 tonnes of organic matter in Portugal, equal to 6% of<br />

total waste produced in 2005, at the four centres where this separation process is in place.<br />

In 2006 we recovered 1247 tonnes of organic matter, representing 11% of total waste produced in 2006 in 8 centres.<br />
