In mid-July 2021, YUTOECO joined hands with Unilever’s Omo, the China Packaging Federation, GREENRIVER and many leading companies in the industry to launch the initiative of “Safeguarding Sanjiangyuan”, to promote knowledge on the classification of plastic packaging and its impact on the environment. The participants visited the source of the Yangtze, Yellow and Lancang rivers to conduct a garbage survey and pick up garbage in some sections of the rivers, to understand the varieties and distribution of garbage and the consequent pollution, and to promote the recycling of plastic packaging.
