Degradable plant containers

A fundamental rethink of materials used in manufacturing of agricultural containers needs to occur to meet the growing global need for food supply in a sustainable manner. Consumers' concern with where their food comes from, how it is grown, and most importantly the environmental impacts of unabated use of plastics and polymeric materials in the food supply chain is an important driver of changes happening in all facets of agriculture including planting containers. This in fact is a major driver of our efforts in developing appropriate technology-based solutions.
Using CtP technology, our plantable containers have substantial content of waste cardboard, bound together and stabilised using our composites formulated from replenishable and benign precursor minerals. These minerals can also be sourced from the processing of diverse saline water and wastewater streams including brine effluents from seawater desalination plants and leachates from many industrial processes. Apart from waste cardboard, our containers can include CO2 gas in their compositions, have high water retention capacity and when placed in soil degrade to become soil conditioners. The commercial rollout of such highly functional agricultural containers has the potential to impart many positive impacts, contributing to this process of rethink of materials in agricultural containers.
