Tyre Recycling End Products — Cross-product Comparison
Side-by-side comparison of nine tyre recycling outputs across three product families — crumb rubber grades, CRMB road-bitumen blends, and reclaimed rubber tiers — showing mesh or dose, buyers, capex tier, and discount versus virgin for each.
| Output | Typical Mesh or Grade | Primary Buyers | Capex Tier | Discount versus Virgin |
|---|---|---|---|---|
| Crumb Rubber — Coarse | 4 to 30 mesh | Civil aggregate; playground surface infill | Tier 1 (lowest) | Not applicable |
| Crumb Rubber — Fine | 40 to 80 mesh | Asphalt blends; moulded products | Tier 1 to Tier 2 | Not applicable |
| Crumb Rubber — Ultra-fine | 100 mesh and finer | Sealants; compound filler | Tier 2 | Not applicable |
| CRMB — Field Blend | 0.5 to 5 percent rubber dose (low-dose) | State PWD road maintenance | Tier 2 (mixer add-on) | Not applicable |
| CRMB — Non-HVB | 8 to 15 percent rubber dose (medium-dose) | NHAI and MoRTH wearing courses | Tier 2 (specialised mixer) | Not applicable |
| CRMB — HVB (High-Viscosity-Binder) | 18 to 25 percent rubber dose (high-dose) | Airports; bridge decks; heavy-traffic highways | Tier 3 (full plant) | Not applicable |
| Reclaimed Rubber — Tier 1 | 70 to 80 percent sulfur reduction | Tyre retreaders; technical rubber goods | Tier 3 (devulcanization reactor) | 10 to 15 percent below virgin |
| Reclaimed Rubber — Tier 2 and Tier 3 | 30 to 65 percent sulfur reduction | Moulded mats; compound filler | Tier 3 (devulcanization reactor) | 25 to 50 percent below virgin |
| Reclaimed Rubber — Tier 4 and Tier 5 | 15 to 25 percent or minimal sulfur reduction | Mud flaps; road-base filler | Tier 2 to Tier 3 | 50 to 70 percent below virgin |

How to read this table
- Blue rows = crumb rubber grades; dark blue = CRMB grades; amber = reclaimed rubber tiers
- Capex tier is relative within this sector: Tier 1 = simplest, Tier 3 = most capital-intensive
- Discount versus virgin applies only to reclaimed rubber — crumb rubber and CRMB are not substitutes for virgin rubber, so the column shows N/A for those rows
- Mesh size for crumb rubber refers to particle size — finer mesh (higher number) = smaller particles = higher processing cost and typically higher sale price
About this table
A tyre recycling business produces one of three broad product families depending on the processing route chosen: crumb rubber (mechanical size reduction), Crumb Rubber Modified Bitumen (CRMB, a road-construction additive), or reclaimed rubber (devulcanized material that partially restores the polymer's properties). Within each family, multiple grades exist — and the capex required, buyers available, and price achievable differ substantially between grades.
Crumb rubber spans three grades by mesh size. Coarse crumb (4–30 mesh) goes to civil aggregate and playground surface infill at the lowest capex tier. Fine crumb (40–80 mesh) serves asphalt blending and moulded rubber products, requiring a mid-tier investment in finer grinding equipment. Ultra-fine crumb (100 mesh and finer) goes to sealants and compound fillers — the smallest market but one that allows better pricing, requiring Tier 2 capex including air classification systems.
CRMB is produced by blending crumb rubber into bitumen using one of three dose levels. Field blend (0.5–5% rubber) is the simplest entry point — a mixer add-on for state Public Works Department road maintenance contracts. Non-HVB (8–15% rubber dose) targets National Highways Authority of India and MoRTH wearing courses, requiring a specialised mixer. High-Viscosity Binder (HVB) at 18–25% rubber dose achieves full rubber-bitumen interaction and serves airports, bridge decks, and heavy-traffic highways — but requires a complete blending plant and Tier 3 investment.
Reclaimed rubber quality is tiered by sulfur reduction achieved in devulcanization — Tier 1 (70–80% sulfur reduction) is nearest to virgin rubber in performance and commands a 10–15% discount versus virgin, while Tier 4–5 material (15–25% reduction) sells at 50–70% below virgin and is used for lower-value applications like mud flaps. All reclaimed rubber tiers require a Tier 3 devulcanization reactor. The source tyre type (truck tread versus passenger versus sidewall) also affects mechanical properties, as detailed in the reclaimed rubber product specs table.
Key insights
- CRMB HVB at 18–25% rubber dose is the highest-value crumb rubber outlet but requires a full blending plant — it is not a simple crumb-rubber upgrade
- Reclaimed rubber Tier 1 (70–80% sulfur reduction) sells at only 10–15% below virgin — the smallest discount of all recycled rubber products, reflecting its near-virgin mechanical performance
- Tier 4–5 reclaimed rubber sells at 50–70% below virgin despite requiring a Tier 3 devulcanization reactor — making the return on that capex highly dependent on volume throughput
- Ultra-fine crumb rubber (100+ mesh) requires air classification equipment to meet the below-0.1% fibre limit — a non-obvious capital item for first-time operators
- NHAI and MoRTH specifications mandate CRMB Non-HVB for national highway wearing courses — creating a government-procurement demand floor that does not exist for plain crumb rubber
Methodology & sources
Product grades, buyer profiles, capex tiers, and discount ranges are based on Indian industry practice as of 2024. Capex tiers (1–3) are relative within the tyre recycling sector and do not correspond to absolute investment ranges (see the Scaling Stages table for absolute figures). Discount versus virgin rubber reflects typical traded prices; actual discounts vary with market conditions and buyer specifications.
