I was reading and inspired by the innovative ideas posted by others such as soluble packaging for plastic products or edible cutlery that I decided to search for a possible alternative to a product that I love and consume on a daily basis -- takeaway drinks.
I found a Thai based company called Universal Bio Pack (UBPack) that uses cassava starch and bamboo fibres (recycled waste from manufacturing chopsticks) in order to create a packaging that is soluble in water in 7 days or can be used for composting when the product is discarded. This technology can be used in multiple ways as its polymer cellular structure allows it to have insulation properties such as hot and cold resistant or hydrophilic (can be used for cosmetics).
