11 Dec 2018 --- Unilever has invested €100,000 (US$114,000) in a new plastic-free laundry tablet as part of its drive to “rethink” plastic packaging. The crowdsourced innovation has the potential to replace single-use sachets of laundry powder, a popular format for laundry detergents in the developing world. Hundreds of billions of the sachets are used every year, ending up in landfill or as litter as there isn't a viable recycling solution for them, a Unilever spokesperson tells PackagingInsights.
