The sponge production process consists of heating a mould of Teflon or silicone to a temperature between 60°C and 70°C, feeding a mixture comprising a plastic material and a reagent into the mould, allowing the mixture to rise for a time less than 30 minutes, and extracting the finished sponge from the mould. In this manner an absorbent sponge is obtained without an impermeable surface skin. The plant comprises a conveyor for conveying a mould to mould heating means, followed by feeding means. The plant then comprises rising means arranged to retain the mould for a time such that the mixture contained in the mould undergoes rising, followed by means for discharging the sponge.
