Tokyo, Japan – ZMP using Econykol biopolyol in its latest self-driving vehicle, the Robocar Walk. The polyol is made by Mumbai-based Vithal Castor Polyols.
MCNS biopolyol finds its way in Robodrive vehicles

Econykol is made from castor seeds, a non-edible plant source. Mitsui Chemicals & SKC Polyurethanes (MCNS) uses it to make a polyurethane that qualifies for BiomassPla certification. MCNS owns 40% of Vithal.
ZMP is using this polyurethane for the seat cushions in the Robocar Walk. It claims this gives a 27% reduction in CO2 emissions compared with regular polyurethane foam.
‘ZMP has worked to create robotics using designs that resonate with people,' said Hisashi Taniguchi, the company’s CEO. ‘We think it’s essential to make use of materials that are both people-friendly and environment-friendly. By adopting Econykol here, we’re able to create robotics that are both people-friendly and eco-friendly – making it possible to provide even more value to our customers.’
