A bio-resin is a resin which derives some or all of its constituent from plants. Rice husk products are 100% natural and do contain lignin, which helps to give the product strength. Not sure if we can use all types of bio waste, would be interesting to develop more products from different types of food waste. There's a company in Germany manufacturing reusable coffee cups from coffee grounds. I love your fun cap concept and my 2 young nephews do too! Wishing you huge success.
Hi Dan, thank you for your response - I understand the initial purchase price can be a challenge, right now some plastic cups are cheaper than cups made from husk / bio resin. With growing demand for natural products we hope to drive down the price. We also need to promote natural products to make them more appealing. I will mail you on private email to discuss how we can collaborate.
