Carbon and energy
We set targets for the reduction of energy consumption and carbon emissions and aim to reduce our use of fossil fuels by energy efficiency and seeking alternative and renewable energy sources. We promote best practices through enabling sustainable construction, inlcuding use of life-cycle analysis and support our customers in this approach.When procuring services and goods that can have an impact on significant energy use we inform suppliers that procurement is partly evaluated on the basis of energy performance.
We have successfully eliminated any virgin fuel oils from our Asphalt Batch Heater Plants at Ettingshall, Groby and Cliffe Hill Quad by replacing the old pilot light with an ignition system. The plants now use 100% reclaimed fuel a 99% reduction in carbon.
- Smart metering
- Half hour metering
- Computerised weigh bridge ticketing
- Custom built software to monitor and track fuel, gas, water and electricity
These enable traceability and evidence of supply and usage across all company operations.
We use an overall energy tracker to produce key carbon/energy data in kilowatt hours per tonne of product produced/kg carbon per tonne of product produce as well as litres of fuel used per heavy plant vehicle.
Energy trackers are also produced at a Unit level for managers, which are then sub divided into each working section of the plant and equipment giving up to date details on energy usage and carbon/kilowatt hour data per tonne of product produced.
All units are set targets and objectives to reduce energy consumption with a 3% carbon reduction on the previous year’s energy usage being targeted through unit, dept and individual KPI’s.
Heavy plant on site at Cliffe Hill (dumpers and shovels) has been replaced with energy efficient machines. This has also included eco driver training, engine management systems and auto tyre pressure monitoring.
Proactive engine management to ensure maximum fuel efficiency includes regular engine oil sampling to monitor engine condition.
SOP’S (standard operating procedures) are issued which cover start up, shut down routines to maximise throughput and energy usage. Also 5s auditing has been implemented with departmental teams made accountable for the efficient and safe use of plant and equipment as well as maximising production and optimising energy usage.
Planned preventative maintenance (PPM) schemes ensure maintained and fuel efficient process plant and mobile plant which optimises energy usage.
Work has taken place to move to low energy “LED” lights, soft starts to replace fluid couplings on conveyor drives where appropriate and campaigns like switch off when not in use. These along with modifications to start up/shut down times of process plant and conveyors etc and additional sub metering all aid the aim of knowing where energy is being used to enable targeting energy reduction.
Conservation of aggregate has taken place with the depletion of long standing stock piles resulting in less blasted rock being required. This along with washing of the products to conserve aggregate with the resultant clay being sold to the brick yards to conserve their virgin clay soils all support our aim to Reduce Re-use and Recycle.
We have design mixes that include a warm mix asphalt produced at a reduced temperature compared to conventional asphalt thus saving on fuel and reducing emissions and a reduction in the level of embodied CO2.
MQP has introduced “Heat Exchangers” into the drier exhaust gases on its Asphalt Batch Plants at Cliffe Hill (Quad), Ettingshall and Northampton. These reduce the temperature of the exhaust gasses which allows the amount of Recycled Asphalt Planings [RAP] to be increased in each batch of asphalt produced. This recycling of the asphalt planings which are removed from the old road surfaces means that energy to quarry virgin aggregate is saved and the finite bitumen resource is also saved. An added benefit to this “heat exchanger” process is that the heat removed by the heat exchanger is not wasted as it is returned into the drier barrel which reduces the burner fuel used to mix each batch of asphalt.
MQP reports on Electrical Energy consumption to the E.A. under the “Carbon Reduction Commitment Energy Efficiency Scheme” [CRC]
This scheme is a UK government scheme designed to improve energy efficiency and cut carbon dioxide (CO2)
The Environment Agency administers the scheme for the UK and regulates the scheme in England.
In each compliance year, an organisation that has registered for CRC needs to do the following:
- collate information about its energy supplies
- submit a report about its energy supplies
- buy and surrender allowances equal to the CO2 emissions it generated
- tell the Environment Agency about changes to its organisation that could affect its registration (designated changes)
- keep records about its energy supplies and organisation in an evidence pack
In addition to the above and due to the size of MQP’s Operations at Cliffe Hill, Wednesbury and Baston Fen the use of energy in the form of “Liquid fuels” [Gas Oil, Kerosene, LPG and Processed Fuel Oil (PFO)] is audited and reported to the European Union Energy Trading Scheme (EUETS) and allowances for Carbon emissions from these sites must be purchased therefore it is in MQP’s interest to minimize their Carbon emissions by rigorous control and investment in more efficient methods and equipment.In addition to “CRC” and “EUETS” The UK Government established ESOS [Energy Savings Opportunity Scheme] to implement EU Energy Efficiency Directive. ESOS is a mandatory energy assessment scheme for organisations in the UK and is administered in the UK by The Environment Agency.
MQP must carry out ESOS assessments every 4 years. These assessments are audits of the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures.
MQP employees attend ECO drive training and equipment management seminars to understand how best to get the value out of the new equipment. They have learnt techniques that could reduce fuel usage by 15%, reducing carbon emissions, minimising wear and tear on the machines, boosting productivity and lowering driver physical and mental fatigue.
Did you know…. a 1% reduction in tyre pressure = 5% more fuel usage
Whether it turns, burns, lights, pumps or crushes, sites are switched on to finding ways to make it run more efficiently. They are focused on channeling ideas coming in from across the business.
A monthly flyer is used to communicate to all employees, highlighting carbon reduction targets/achievements/initiatives/training along with the same for safety.
