| Aggregates and ready-mix concrete |
As with the cement sector of our operations, a Plant Environmental Performance (PEP) self-assessment tool is used in monitoring and reporting of performance. It helps us identify strengths and weaknesses, and is used in environmental business planning: for example, for the development of environmental programs, action plans, capital expenditure and budgeting. A Group-wide database establishes reporting and communication parameters, with Group and Group company progress able to be tracked and internally benchmarked. This case study on ready-mix concrete initiatives in Europe demonstrates our approach. Aggregate quarries provide similar challenges as limestone operations, including noise, blast vibration, ground and surface water issues and visual impact. In 2006, eight of our 345 quarries reported non-compliance with laws or regulations – total fines amounted to CHF 39,000 (2005: nine of 337; CHF 83,500). Dust control and water management are key issues for ready-mix concrete plants. The reduction of fugitive dust emissions is possible for many sources – for example, bag filters for cement unloading. In 2006, 44 of our 892 ready-mix plants reported non-compliance – total fines amounted to CHF 176,000 (2005: 21 of 864; CHF 90,500). More and more Group companies are making use of recycled concrete to save virgin aggregates. Figures for total quantities recycled will be included in future reporting cycles. This Canadian case study suggests what is possible. The following table presents the 2006 performance for these business sectors. |
