Aggregates 

Opening up new opportunities across the Aggregates sector


The aggregates industry produces 2.6 Mt of CO2. There are 1,300 quarries in the UK, with rock focused in the West and North, sand and gravel in the southeast and a number of super quarries in the East Midlands and Scotland. Markets are regional but as demand is focused around urban centres there are large transport flows of primary aggregates around the UK.

Key findings from the Carbon Trust Report

  • Transport accounts for 35% of CO2 emissions in the sector
  • Asphalt production is responsible for 25% of emissions

By working closely with key players in the aggregates sector, the Carbon Trust analysed detailed energy data from the asphalt and quarrying processes and identified four challenge areas that will lead to energy and cost savings for businesses in this sector.

Industrial Energy Efficiency Challenge

We are interested to hear from companies interested to undertake an innovative challenge in the aggregates sector:

Integrated Asphalt Process Improvement to Produce Lower Temperature Asphalt Containing a High Percentage of Reclaimed Asphalt Pavement


This project will demonstrate an alternative method to produce asphalt at lower temperatures using an innovative foaming technology and, if appropriate, a novel dryer that uses a much higher proportion of recycled asphalt pavement (RAP). This is likely to be a 21 month project. The funding available from the Regional Growth Fund is £162,000. Total project cost is likely to be £406,000.

Implementation of Heat Recovery for Pre-Heating of Combustion Air.


This project will demonstrate the implementation of a novel heat exchanger technology to pre-heat combustion air (HRC) on an asphalt plant to determine whether this can be implemented successfully and at reasonable cost on asphalt plants. Rather than use existing technologies for HRC, such as plate heat exchangers, the project will use a novel “heat pipe” technology to recover thermal energy from exhaust gases for pre-treatment of the combustion gases. The funding available from the Regional Growth Fund is £106,000. Total project cost is likely to be £264,000.


 

Additional funding may be available through the Energy Efficiency Financing Scheme, a £550m fund established between the Carbon Trust and Siemens Financial Services. For further details, see Energy Efficiency Financing.
