Circular Economy in injection moulding

Efficient plastics recycling - sustainable production

Together with other market participants, ENGEL has been actively involved in the Circular Economy and the reduction of the CO2 footprint for years. This goal requires close cooperation across the whole value chain. For ENGEL, supporting its customers along the entire product life cycle is a key concern: from component design and sampling to production and maintenance & service.

Technologies for plastics recycling

Each participant in the value chain has a specific role to play. As an injection moulding machine manufacturer and system solver, ENGEL assumes responsibility for three areas: The overall efficiency of the injection moulding production cell, the digitalisation of injection moulding processes and processing technologies.

Advantages with us as a partner in the area of Circular Economy
Reduction of the CO2- footprint thanks to efficient overall systems

Whether servo-hydraulic, hybrid or fully electric: ENGEL injection moulding machines are among the most efficient of their size and performance class on the market. Servo-hydraulic machines already consume less than 60% of a hydraulic injection moulding machine with a fixed displacement pump. With all-electric injection moulding machines, power consumption can even be more than halved on average. With a precisely coordinated temperature control solution, even more energy-saving potential can be achieved.

Digitalisation to increase energy efficiency

The self-optimising injection moulding machine is a key driver of Circular Economy. It is about avoiding rejects and increasing energy efficiency. Our digital solutions from the inject 4.0 programme help to automatically reduce influences on the process. Recyclates can thus be used for a wider range of applications than before.

Consistently high product quality to avoid recycled material

The processing of plastic waste usually requires less energy than that from fossil sources. The use of recycled material therefore has a direct positive effect on the CO2 balance. This is why ENGEL's in-house development focuses on solutions for recycling and upcycling. Successful examples include the skinmelt and foilmelt technology with up to 100% recycled raw material or the two-stage process in which plastic waste is processed as regrind directly after grinding.

Simple upgrades and retrofits for longer machine use

ENGEL offers facilitated retrofits and assists with the appropriate disposal of the machine. We pursue the goal of developing a practical concept for upgrading older machines with, for example, more energy-saving drive or control systems. In this way, inefficient machines are to be reconditioned and further used instead of being disposed of.

More safety in handling recyclate through training courses

Due to the high complexity of the products and materials, it is important to conduct regular training. ENGEL's Circular Economy training courses range from the reduction of wear materials to the correct use and handling of recyclates. ENGEL offers analyses and consultations especially for recycled materials, which have higher fluctuations in their properties.

Circular Economy is based on the interplay of all market participants. In order for the process chain to function seamlessly, it is important that each individual step within the overall process is economical. At this point the circle closes to the optimisation of energy consumption, CO2 balance and thus the cost structure. The plastics industry must act quickly and take advantage of the opportunities opened up by innovative technologies.

Innovative projects in the area of Circular Economy

100% recyclable e-bike frames, frisbees made from old collected caps and transport boxes that consist of an over 50% recycled material core: We develop Circular Economy solutions for and together with our customers, which also prove themselves in practice.

    • technical moulding
    100% recyclable e-bike frame

    The first pure injection-moulded bicycle frame with advanced thermoplastic composites is 100% recyclable.

    • technical moulding
    Transport boxes with recycled core material

    With the help of ENGEL skinmelt technology, up to 50% recycled material can be used in the core of the transport box.

    • technical moulding
    Frisbees made from recycled caps

    The drink stoppers collected on the JKU Linz campus were recycled and made into Frisbees, demonstrating circular economy with a simple example.

Customer AVK uses ENGEL's two-stage process to increase efficiency

ENGEL's two-stage process means that a complete process step can be saved when processing plastic flakes, because the recyclate is processed in the injection moulding process without granulation. The company AVK Plastics BV uses this technology to produce new pallets from recycled material. This technical innovation increases efficiency in production and saves valuable energy.
