Czech scientists turn chicken feathers into liquid fertilizer

Every year, Czechs consume millions of chickens, leaving behind tons of feathers as a by-product. The feathers typically end up in incinerators or on landfills. Czech scientists have now come up with a way of repurposing this by-product – turning it into liquid fertiliser.

It is estimated that the Czech chicken industry generates about 100 million tons of kilogrammes of feathers each year. The waste is either incinerated, creating large amounts of CO2, or end up in landfills, where they take years to decompose.
