Eco Curve Retrofit Conveyor Belt
A recyclable modular belt retrofit that converts existing curved belt conveyors from unrecyclable PVC and polyester belting to fully recyclable polypropylene — installed in situ, with minimal disruption, across logistics, manufacturing and airport baggage handling environments in the UK.
Eco Curve Retrofit Conveyor Belt
The M2i Eco Curve (also referred to as the Eco Curve Retrofit Kit, Recyclable Curve Belt, Curved Belt Upgrade or Power Curve Retrofit) is a recyclable modular belt solution that upgrades existing curved belt conveyors without replacing the whole unit.
Most curved conveyors run on PVC- or polyester-backed synthetic belts. These traditional belts cannot be recycled and are typically sent to landfill at the end of their life. The Eco Curve replaces that running surface with a fully recyclable polypropylene modular belt, fitted to the conveyor you already own.
Because curves are usually part of a live, operational system, full replacement is often impractical and disruptive. The Eco Curve is supplied as an internally suspended kit of parts that mounts inside the existing chassis, converting a synthetic belt curve to a modular belt configuration in situ. In many cases the conveyor returns to service the same day.
The Eco Curve was developed in partnership with Ammeraal Beltech, a global leader in conveyor and process belting, combining M2i’s modular curve engineering with proven recyclable modular belt technology.
The Retro Kit System is a mechanically suspended retrofit solution designed to replace the existing running surface, belt support, and bearing positions typically required by synthetic belts. It introduces a structurally robust wear strip running deck, complete with integrated belt support and guide bearings, optimized for use with modular belts along the inner edge.
Rapid Installation due to the modular design and built-in adjustability, the Retrofit Kit can be installed with minimal disruption. In many cases, the conversion is completed quickly enough to allow the conveyor to return to service the same day

By upgrading existing curves with a fully recyclable modular belt, the EcoCurve extends the life of infrastructure already on site and removes it from the end-of-life category — supporting international sustainability targets without full system replacement.
Patented WO2023284927 – Belt and Kit for the adaption of existing PVC based multi bearing edge running belts to inside edge bearing running modular belt
Engineered around a laser-cut steel inner ring that acts as an independent support plate, the Eco Curve reuses the existing conveyor chassis while providing the precise belt support, wear strips and bearing positions a modular belt requires. The result is a sustainability upgrade that extends the life of equipment already on site, rather than scrapping and replacing it.
Key Features
- Suitable for 1550mm CTR Line or 1000mm Inside Radius Belt Curves
- The Inner Ring Plate enables cross-members to be positioned independently of the existing chassis
- It removes the curve from the "end-of-life" category by extending lifecycle
- V0 Fire Retardant Rated Belt
- Conveyor Angles – 30, 45, 60 and 90
- Conveyor speed up to 2.0 m/s
- Structural Loading 100kg/m (Of the Deck-Subject to the original Chassis)
- Baggage weight up to 60 kg/m
- Retrofit kit — upgrades existing curved conveyors without buying a new unit
- Fully recyclable polypropylene modular belt replaces unrecyclable PVC and polyester belts
- Installed in situ with minimal disruption — in many cases back in service the same day
- Fewer component parts than a synthetic belt curve, removing chains and outer edge guide bearings in many cases
- Sectionally repairable, then reground and recycled at end of life
- Laser-cut steel inner ring for independent, fully adjustable belt support
- Developed with Ammeraal Beltech for proven modular belt performance
By converting existing curves to recyclable modular belting, the Eco Curve removes ageing conveyors from the end-of-life category and brings live systems in line with corporate and international sustainability targets — without the cost and downtime of full replacement.
Industry Use of the Eco Curve Belt Conveyors
The Eco Curve can be fitted across material handling environments where curved synthetic belt conveyors are already in service and a recyclable, lower-maintenance upgrade is required.
Curved conveyors throughout screening, sortation and reclaim run almost continuously. The Eco Curve upgrades these curves to recyclable modular belting with minimal downtime — M2i Eco Curve belts have run at major UK airports including Heathrow, Gatwick and Birmingham, with the original Heathrow installation in service for four years without belt replacement.
In high-throughput distribution centres, the Eco Curve replaces worn synthetic curve belts with recyclable modular belting, reducing maintenance and improving the sustainability profile of existing parcel handling lines.
Warehouse & Fulfilment Systems
Curves linking storage, picking and dispatch can be upgraded in place, extending the working life of installed conveyors while cutting belt waste sent to landfill.
Manufacturing lines use curved conveyors to move product between processes. The Eco Curve retrofit delivers a recyclable, lower-maintenance running surface without re-engineering the line.
M2i curved conveyors integrate seamlessly with wider modular conveyor systems and automation platforms, delivering scalable solutions for material handling applications across the UK.
A Direct Upgrade for Existing Curved Conveyors
Supplied as a kit of parts, the Eco Curve is designed to adapt to existing synthetic belt curve conveyors that suit a modular belt application.
The retrofit typically works alongside:
- Existing curved conveyor chassis (reused, not replaced)
- Modular straight conveyors
- Conveyor merges and transfers
- Sorting and scanning systems
- Airport baggage handling, parcel and industrial conveyor lines
Typical Curve Retrofit Capabilities
While every retrofit is surveyed and configured to the existing unit, the Eco Curve typically delivers:
- Conversion of synthetic belt curves to recyclable polypropylene modular belting
- In-situ installation that reuses the existing chassis
- A reduced parts count and simpler ongoing maintenance
- Full vertical and in-arch adjustment to set the belt running surface and clear existing fixtures
Eco Curve Recyclable Belt Retrofit
The Eco Curve replaces the synthetic running surface of an existing curve with a recyclable modular belt, supported on a laser-cut steel inner ring.
Serpentine wear strip holders, offset from the turning centre to reduce belt wear, mount to adjustable cross members for precise belt support through the arc.
This kit-based approach lets curves already in service be upgraded in place, extending equipment life while removing unrecyclable belting from the waste stream.
Sustainable by Design
The Eco Curve helps reduce lifecycle costs and waste across material handling infrastructure.
Where a synthetic belt would be scrapped to landfill, the modular polypropylene belt can be sectionally repaired, then reground and recycled — supporting recyclable-material and energy-efficiency goals across large conveyor networks.

Precision Engineering for a Reliable Retrofit
The Eco Curve kit is engineered to carry the loads the conveyor is exposed to, with serpentine offset wear strip mountings, clamped cross beams, upper and lower adjustable bearing supports and an inner offset support ring.
The laser-cut inner ring fixes back to the original chassis and adjusts vertically, so the belt running surface can be set accurately while clearing existing fixtures — giving a reliable, long-life upgrade with minimal installation disruption.
The Inner Ring Plate is a pivotal part of the design: it lets the cross-members be positioned independently of the existing chassis, giving the adaptability needed to retrofit a wide range of curves.
