Conceptual Plant Layout — Zone Planning
A seven-zone conceptual plant layout for a tyre recycling facility — covering reception and sorting, pre-treatment, dirty and clean processing, storage, utilities, and administration — with the key functions and requirements for each zone.
| Zone | Functions | Key Requirements |
|---|---|---|
| Reception / Sorting Zone | Weigh bridge, tire unloading, visual inspection, sorting by type and size, temporary staging | Vehicle access, covered staging area, drainage |
| Pre-treatment Zone | De-beading, de-steeling, initial shredding, size reduction | Dust containment, noise barriers, metal scrap collection |
| Processing Zone — Dirty | Primary shredding, grinding, devulcanization reactors | Heavy foundations, ventilation, chemical storage |
| Processing Zone — Clean | Refining, screening, classification, CRMB blending | Temperature control, quality testing area |
| Storage Zone | Raw material storage, finished product storage, steel/fiber byproduct storage | Fire separation, covered storage, inventory management |
| Utility Zone | Power distribution, water treatment, boiler, compressors, maintenance workshop | Central location, easy access for servicing |
| Administrative Zone | Offices, lab, canteen, parking, security | Separated from processing, upwind location |

How to read this table
- Each row is one functional zone; the columns describe what activities happen there and what infrastructure it requires.
- Zones should be arranged so that material flow from Reception (input) to Storage (output) is roughly linear — backtracking increases forklift and vehicle conflicts.
- Processing Zone Dirty and Processing Zone Clean are separated because clean product quality (final crumb rubber grade) must not be contaminated by shredding dust or rubber particles from the dirty zone.
About this table
Plant layout design for a tyre recycling facility requires separating incompatible operations — dusty shredding cannot be adjacent to finished product storage; chemical storage must be separated from administrative areas; vehicle access for heavy trucks cannot conflict with forklift movement in the processing area. This table maps seven functional zones, their operations, and the key infrastructure requirements for each zone.
The Reception and Sorting Zone is the entry point — vehicles arrive with whole tyres, tyres are weighed on a weigh bridge, visually inspected for tyre type and condition, and sorted by size and category before staging for pre-treatment. This zone must accommodate large-radius vehicle turning for multi-axle trucks and needs covered staging to prevent waterlogged feedstock degrading in monsoon. The Pre-Treatment Zone handles de-beading (removing steel bead wires), de-steeling (separating steel belts), and initial shredding — all high-noise, high-dust operations requiring noise barriers and dust containment to comply with SPCB consent conditions and protect workers. Metal scrap collection bins for steel bead and belt are a required element of this zone.
The Processing Zone — Dirty houses primary shredding, secondary grinding, and (for reclaimed rubber plants) devulcanisation reactors. Heavy machinery foundations, ventilation for rubber odour and particulates, and chemical storage for devulcanisation chemicals are required here. The Processing Zone — Clean handles refining, screening, classification of crumb rubber by mesh size, and CRMB blending — operations where temperature control and quality testing proximity are important. Storage requires fire separation between feedstock (whole tyres are a fire hazard) and finished products, with covered storage protecting crumb rubber from moisture absorption. The Utility Zone (power distribution, water treatment, boiler, compressors) benefits from central location for short cable/pipe runs. The Administrative Zone must be upwind of the processing areas and physically separated — rubber dust and odour exposure must be minimised for office workers and laboratory staff.
Key insights
- Fire separation between the tyre storage zone and all other zones is mandatory — whole tyre storage fires are extremely difficult to extinguish and can cause complete plant loss.
- The Processing Zone Dirty and Processing Zone Clean must be physically separated — contamination from the shredding and grinding area reaching the finished product storage destroys product quality.
- The Reception Zone must be designed for multi-axle truck access — insufficient vehicle turning radius is one of the most common plant design errors in first tyre recycling plants.
- The Administrative Zone location upwind of processing is not just a comfort feature — it is a SPCB requirement for industrial plants to minimise worker exposure to process emissions in non-processing areas.
Methodology & sources
Zone functions and requirements described represent standard plant layout principles for tyre recycling facilities as of 2024. Actual zone areas, separation distances, and infrastructure requirements depend on plant scale, local SPCB consent conditions, and fire authority requirements. Plant layout should be developed by a qualified industrial facility architect familiar with tyre recycling or rubber processing plant design.
