WST utilizes water as a medium combined with mechanical separation performed within a modular apparatus, the WST system focuses on efficiently separating mixed organic and inorganic household waste. The incoming waste is processed by soaking, separating, melting and precipitating to achieve a very high accuracy in separation. This results in an output stream that is cleanly separated into several defined categories, providing sufficiently pure material for on- or off-site recycling. This high level of recaptured recyclable material greatly reduces the quantity of waste for final landfill, effectively solving today's solid waste crisis. More than 80% of the household waste can be recycled after being sorted by WST system.
