Problem
Traditional asphalt production relies heavily on fossil fuels and virgin polymers, contributing to significant carbon emissions and environmental degradation. The disposal of waste plastics also presents a major environmental challenge.
Solution
MacRebur offers a sustainable solution by developing and supplying polymer products, MR6 and MR8, made from waste plastics for use in asphalt road construction. These products replace a portion of the bitumen binder typically used in asphalt mixes, reducing the reliance on fossil fuels and diverting plastic waste from landfills. By incorporating these polymers, asphalt producers can achieve both financial and environmental savings while maintaining or improving the performance and durability of the road surface. MacRebur's technology allows for the creation of more sustainable and cost-effective road infrastructure.
Target Audience
MacRebur's primary customers are asphalt producers and road construction companies seeking to reduce their environmental impact and lower production costs.
Features
- MR6: A polymer blend designed to modify asphalt and reduce deformation failures, typically used in place of polymer modified bitumen (PMB) on motorways and heavily trafficked areas.
- MR8: A polymer blend designed to extend the binder in asphalt mixes, used as a direct replacement for neat bitumen on standard traffic roads and footways.
- Carbon savings: MR6 saves an average of 11.32 kgCO2e per tonne of asphalt, while MR8 saves an average of 4.65 kgCO2e per tonne of asphalt.
- Dry mixing: Both MR6 and MR8 are typically dry mixed at asphalt plants, simplifying the integration process.
- ISO 14064-3 verification: All carbon data is verified in accordance with ISO 14064-3, ensuring accurate and reliable sustainability reporting.
