| Recycling concrete and asphalt debris – St Lawrence Cement Canada |
|
Description By recycling concrete and asphalt debris, St Lawrence Cement (SLC) Canada offers its customers – including government, municipalities and private owners – a dependable and economical ‘green’ alternative to virgin aggregates. |
Objectives
SLC aims to recycle as much concrete as possible. As well as environmentally responsible, it represents sound economic sense – for example, most of its concrete plants manage unutilized concrete by casting it into concrete blocks that are resold or by placing it in thin layers in the yard for subsequent crushing and resale as manufactured aggregate.

Activities Recycling can take place on construction sites or at SLC construction yards. For example, as part of the company’s contract at Lester B. Pearson International Airport in Toronto, SLC recycled and crushed 450,000 tonnes of concrete rubble for use as road base materials in the preparation of new aprons. |

Results SLC’s concerted recycling efforts are bearing fruit. In 2005, the company sold around 434,000 tonnes of recycled concrete as aggregate, mainly in Ontario. In Quebec, SLC’s RMX subsidiary recycled some 190,000 tonnes of concrete into new product. More than 168,000 tonnes of asphalt was also recycled in Ontario in 2005. |
