High quality ABS compound produced using waste plastics

A high gloss ABS compound has been produced from a mixture of recycled and virgin materials, impact modifiers and thermal stabilizers, with the high-quality compound potentially suitable for applications in new Electronic and Electrical Equipment.

The requirements for ABS were defined by Philips, who require a high gloss ABS grade for their Personal Health products. Taking into account the requirements defined by Philips, a compound of black, high gloss ABS including up to 30 % of recycled material has been developed and tested. Recycled ABS for the compound was derived from waste ICT equipment and Small Domestic Appliances (SDA) at recycler Coolrec, with the first compounding trials at Sitraplas indicating that the flakes resulted in ABS compounds with high impact and excellent surface gloss and were comparable to virgin reference products. Work continues to optimize the compound and assess implementing production.

In addition to the industrial ABS provided by Coolrec, both ABS recovered from the heavy fraction of shredded SDA/ICT and ABS from TV and computer monitors using IVV’s Creasolv process is undergoing testing and optimization. Full technical data is expected to be released in the final months of the project.

The project partners toured the facilities of battery recycler, Accurec.

The project partners toured the facilities of battery recycler, Accurec, who have designed and tested an innovative microwave treatment technology for Li-ion battery waste as part of the CloseWEEE project. The process enables recovery of critical raw materials – metals and graphite – which with appropriate treatment, can be re-used in battery manufacture or in other applications.

Accurec has long been involved in the recycling of batteries – Founded in 1995 the company now processes 4.5 million kilograms per year of NiCd, NiMH and Li-ion batteries. As part of the CloseWEEE project, Accurec has designed and tested a safe, and environmentally friendly, innovative microwave treatment technology for Li-ion battery waste. In the process, the batteries undergo a pretreatment of discharging and mechanical processing. The Li-ion battery material is then fed into a microwave furnace where the material is heated up rapidly and the organics (electrolytes and separators, etc.) are pyrolyzed/evaporated. It produces electrolyte-free material for subsequent hydrometallurgical treatment for recovery of metals (Co, Ni, Mn, Li) and graphite. For more information, get in touch at info@accurec.de.
