Local reserves of natural aggregates, as well as suitable sites for land-filling of waste in Hampshire are becoming increasingly scarce. These factors are compromising the ability of the local construction industry, and are flagged in the Minerals and Waste Development Framework accordingly.
Hampshire County Council has therefore collaborated with the local aggregate, construction and waste industries and other stakeholders through the Material Resources Strategy to sustainably meet the development needs of Hampshire. As a result, joint objectives have been set to maximise the tonnage of aggregate recovered from waste, and minimise the tonnage of construction waste confined to land-fill.
Hampshire County Council has taken the lead in pinpointing the use of recycled aggregates across its own construction activities as widely as possible and promoted their use. The following are examples of the activities pursued:
- Utilisation of soil stabilisation instead of of granular material for road foundations
- Preferring the use of recycled granular materials
- Utilisation of recycled aggregates in concrete mixes
- Re-use of road planings in cold mix asphalt materials
- Finding uses for aggregate recovered from Incinerator Bottom Ash
- Recycling high quality aggregates used for surface dressing operations
The Environment Department of Hampshire County Council has managed to increase its use of recycled aggregates and reduce the tonnage of material sent to landfill by over 40,000 tonnes per annum through pursuing the above-mentioned activities with working partners over a period of three years.
Furthermore, due to consequential investments made by local companies, Hampshire and the immediate vicinity have attained the following:
- Regular recycling of spent rail ballast
- Several local companies producing good quality granular materials from skip waste
- Several utility operations effectively recycling their own arisings
- A local company conducting soil stabilisation works
- Two producers of washed recycled aggregates suitable for concrete
- A plant producing cold mix asphalt materials
- A plant routinely recovering aggregate from the ash originating from Hampshire’s three energy from waste plants.
