The waterproof material on the cloth diaper pail liner from Rumparooz is TPU, not PUL. PUL is a polyester fabric that has been laminated with a poly-urethane laminate using a solvent and chemical process. This process off-gases harmful toxic fumes that destroy the building that the fabric is produced in. Biodegradable TPU is solvent-free. Biodegradable TPU is a polyester fabric that has been laminated with a thermoplastic polyurethane using a heat bonding process. This process is low in toxicity and is better for the natural environment. Both the TPU laminate and the polyester fabric the laminate is applied to are biodegradable. When composted they will biodegrade in 4-5 years.
