Welcome to the Aggregates Carbon Reduction Portal. Welcome to the Aggregates Carbon Reduction Portal. The resources on this website will explain how your business can maximize its carbon reduction, saving you money in a highly competitive environment. Achieving carbon and energy reduction is a journey, rather than a single step.
Achieving carbon and energy reduction is a journey, rather than a single step. The journey navigator on this website replicates the process. You can choose whether to complete the whole journey or just dip into individual stages, depending on the point you think your business has reached.
Similarly, it might be necessary to involve third parties, such as contractors or specialists, in the approval and implementation of carbon and energy reduction ideas. To show that ideas have been worth pursuing it is important for their effectiveness to be evaluated following implementation, but that is the subject of the next journey stage.
An effective carbon and energy reduction scheme relies upon the specialist knowledge of those who use the equipment. Without new ideas from staff on how to cut energy consumption and carbon emissions it will be very difficult to make any savings.
Specific conclusions of the present work are drawn based upon the experimental results i It was determined that CO 2e emissions decrease slightly by increasing the percentage of recycled coarse aggregates in the concrete mixtures, indicating that the use of this material has little influence on the reduction of the carbon footprint in the
Embodied carbon. Aggregate Industries is leading the way in helping clients to make sustainable design and purchasing decisions by providing carbon calculations and third party verified productspecific Environmental Product Declarations EPDs.We recently partnered with BASF Construction Chemicals to create a suite of EPD based on Life Cycle Assessment LCA calculations using the BASF tool
The Canadian company CarbonCure Technologies has developed a process that injects waste CO 2 into a typical concrete production process, effectively replacing a small amount of cement with CO 2 without compromising the concretes strength or integrity. Once in the mix, the CO 2 changes into calcium carbonate, the chemical equivalent of the limestone used in the production of conventional cement.
The development of carbon capture and storage technology will be critical to the industrys longer term ability to reduce these latter emissions. MPA has worked closely with The Carbon Trust to embed carbon reduction into the aggregates sector, leading to the production of an Aggregates Carbon reduction microsite with open access here
Research outcomes revealed, as expected, that carbon dioxide equivalent emissions decreased slightly as the use of recycled aggregates increased. Emissions for concrete with 0.5 wc were between
A Marginal Abatement Cost Curve MAC curve or MACC is a succinct and straightforward tool for presenting carbon emissions abatement options relative to a baseline typically a businessasusual pathway. A MAC curve permits an easy to read visualization of various mitigation options or measures organized by a single, understandable metric
Concrete as a Carbon Sink Recycled Aggregates and or air separation and size reduction in a crusher to aggregate sizes, crushed concrete can be used as new concrete for pavements, shoulders, median barriers, sidewalks, Using recycled aggregates instead of extracted aggregates would qualify as postconsumer. Because concrete is an
The Carbon Trust commissioned a strategic report which identified that 30 of the longterm UK targets for carbon reduction in the Aggregates sector could be realised via behavioural and process change. Sysdoc led an awardwinning programme with the five major Aggregates organisations, delivering carbon savings well above projected targets
The Aggregates Carbon Reduction Portal uses an innovative journey navigator to replicate the passage towards carbon and energy reduction for a crushed rock quarry, sand and gravel quarry or asphalt plant. The website is userfriendly and a video on the homepage clearly explains how it works.
Organic carbon in the microaggregates is less Meng et al. 92 showed that the main reason for the decline of aggregate stability and the decrease of waterstable aggregates were the reduction
While pristine prairies clearly sequester higher carbon levels than restorations or agricultural fields, restoration efforts may create ecosystems that can contribute significantly to a reduction in atmospheric CO2. Soil organic matter plays an important role in C accumulation in restored prairies Kucharik et al., 2006 McCarthy et al., 2008.
Upcycled Aggregate is a byproduct of demolished and returned concrete that has been through a calcium extraction process for Blue Planets carbon dioxide sequestered limestone. This aggregate is useful in most concrete mixes, and is well indurated and harder than virgin aggregates due to the uniform process of Blue Planets reformation step.
The transportation of aggregates from quarry to production site raises significant concerns over carbon emissions. A considerable body of literature argues that if more freight could be carried on the rail network, substantial reductions in carbon footprints could be made.
