What MacRebur does
MacRebur Limited is a UK-based materials science company founded in 2016 by Toby McCartney in Lockerbie, Scotland. It develops and sells two proprietary polymer asphalt additives — MR6 (a polymer modifier replacing virgin polymer in polymer-modified bitumen) and MR8 (a binder extender replacing neat bitumen) — both manufactured from recycled waste plastics. Products are dry-mixed at asphalt plants and deliver ISO 14064-3 verified carbon savings of 11.32 kgCO2e per tonne (MR6) and 4.65 kgCO2e per tonne (MR8). MacRebur also designs and builds its own recycling machines and addition systems in-house.
The company serves three primary customer segments: government transportation departments (e.g., Virginia DOT, New Jersey Turnpike, New York City DOT), commercial infrastructure operators (e.g., Auckland International Airport, Sainsbury's, Barcelona bus lanes), and asphalt producers and plants. It sells MR6 and MR8 as a direct product replacement (one-time product sales) and generates additional revenue through a network of licensed manufacturers and exclusive regional distributors covering 30+ countries, including Agustí y Masoliver (Catalonia), Plastic Road OÜ (Baltics), The Sparksco (Southern California), Solution SE (New Zealand), Dorsa Group (Moldova/Romania/Ukraine), and Setia Bintang Engineering (Malaysia/Thailand).
MacRebur has raised over £7 million across three crowdfunding rounds since incorporation plus institutional capital from Pario Ventures. Operations span the UK headquarters (Lockerbie), a new manufacturing facility in the Republic of Moldova opened March 2024, and a Turkish subsidiary (MacRebur Turkey Limited). The company holds ISO 9001, ISO 14064-3, and EPD certifications, has secured national product approvals in markets including Malaysia and Bahrain, and has a small management team led by co-founders Toby McCartney, Gordon Reid, and Nick Burnett.

MacRebur product offering
Product offeringCore offering
MacRebur manufactures and sells two proprietary sustainable polymer asphalt additives — MR6 (polymer modifier) and MR8 (binder extender) — made from recycled waste plastics. These products are dry mixed at asphalt plants as direct replacements for virgin polymers and neat binder, used in road construction, motorways, airports, and heavy-traffic infrastructure across more than 30 countries.
Product overview
MacRebur is a single-product-line company offering two sustainable polymer asphalt additives: MR6 and MR8. Both products are mixed into asphalt at asphalt plants during production to replace virgin polymers and extend bitumen binder. MR6 targets high-specification applications where polymer modified bitumen is required (motorways, heavy traffic), while MR8 addresses standard road construction applications. Both products provide carbon savings verified to ISO 14064-3 standards and offer asphalt producers both financial savings and environmental benefits.

Brands
- MR6: Sustainable polymer product manufactured from a mix of polymers designed to modify asphalt and reduce deformation failures or increase stiffness. Provides direct replacement to virgin polymer used in production of polymer modified bitumen (PMB). Saves 11.32 kgCO2e per tonne of asphalt on average.
- MR8
Products and services
- MR6 MR6 is a sustainable polymer asphalt additive manufactured from a mix of recycled polymers, designed to modify asphalt and reduce deformation failures or increase stiffness. It serves as a direct replacement for virgin polymer used in polymer modified bitumen (PMB) production, typically dry mixed at asphalt plants for motorways, heavy duty base courses, and surface courses subject to heavily loaded traffic. Saves an average of 11.32 kgCO2e per tonne of asphalt.
- MR8 MR8 is a sustainable polymer asphalt additive manufactured from a mix of recycled polymers, designed to extend the binder in any asphalt mix. It is used as a direct replacement for neat (unmodified) binder, typically dry mixed at asphalt plants for standard traffic roads, footways, and all base, binder, and surface course asphalt materials. Saves an average of 4.65 kgCO2e per tonne of asphalt.

MacRebur competitors and assessment
Company assessmentEmerging players
- CarbonCure Technologies: A Canadian cleantech company injecting recycled CO2 into concrete mixes to reduce cement carbon footprint. Comparable as a sustainability-driven construction-materials technology company selling verified carbon reduction to infrastructure buyers — same procurement narrative as MacRebur, but in concrete rather than asphalt.
Broad incumbents
- Kraton Corporation (DL Chemical): Producer of styrene-butadiene-styrene (SBS) and other synthetic polymers widely used as virgin polymer modifiers in PMB production. Comparable to MacRebur because SBS-based modifiers are the direct incumbent product that MR6 displaces in asphalt mixes.
- Shell Bitumen: A division of Shell producing conventional and polymer-modified bitumen binders for global road infrastructure. Comparable as a large incumbent supplier to the same asphalt producers and DOT customers that MacRebur targets, and a potential long-term threat if it launches its own recycled-polymer modifiers.
- Ingevity Corporation: A specialty chemicals manufacturer with a road-technologies division producing asphalt additives and emulsions, including bio-based modifiers. Comparable to MacRebur as an established supplier of performance-enhancing asphalt chemistry to highway departments and asphalt producers.
- TotalEnergies Bitumen / Polymers: A major integrated energy company supplying bitumen binders and specialty polymers for road construction across Europe and globally. Comparable as an incumbent with the scale and balance sheet to enter recycled-polymer asphalt modification if it chooses to compete directly with MacRebur.
- Colas SA: A leading French road construction and bitumen derivatives group with global operations, producing modified binders and asphalt mixes. Comparable as an established buyer/developer of polymer-modified binders that could adopt or compete with MacRebur's recycled-plastic additives.
- Dow Chemical (Dow Plastics): A diversified chemical major with packaging and infrastructure plastics, already cited alongside MacRebur in plastic-road coverage. Comparable as a much larger player that could commercialize recycled-polymer asphalt additives at scale, posing a direct competitive threat.
- Orbia (Vestolit / Polymer Solutions): A global specialty chemicals group with polymer and fluorinated specialties businesses, also named alongside MacRebur in plastic-road news coverage. Comparable as a large materials company that could supply recycled-polymer road additives or acquire emerging players.
Direct peers
- Iterchimica: Italian producer of additives and modifiers for asphalt, including recycled-plastic-based modifiers under its Gipave product line. Direct peer to MacRebur: serves the same asphalt-producer customer base with sustainable polymer modifiers and competes for the same road-construction tenders in Europe.
- PlasticRoad (KWS / VolkerWessels): A Dutch partnership between VolkerWessels and KWS Infra that designs and pilots modular road structures made from recycled plastics. Direct peer to MacRebur: both sell recycled-plastic road concepts to public-infrastructure buyers with comparable sustainability messaging.
