Non-toxic, eco-friendly, marine safe, and dissolves in hot water
Advent Hydrobag begins life as an agent called Ethylene, a hydrocarbon which has the formula C2H4 or H2C=CH2.
Ethylene can be petro-derived or sustainably sourced from biomass. It is then converted into polyvinyl alcohol (PVOH). Colourless and odourless, PVOH has been used for years in surgical stitches.
It is hydrophilic (dissolvable in water) and has enhanced biodegradation properties. Independent studies have shown that it is extremely biodegradable in aerobic (soil, compost, freshwater) and anaerobic (sewerage, some landfills) conditions.
However, the real breakthrough comes from the production of multifunctional polyvinyl alcohol monolayers- which causes it to break down- into hydrogen, carbon, and oxygen- even faster.
This is converted into water-soluble polymers which then becomes Advent Hydrobag.
