Liquid Waste Solidifier: Absorbent Boxes

Polymer Waste Management

Absorbent boxes are made by Recyc PHP. They contain sodium polyacrylate, a recycled material in our facilities from industrial releases of hygiene products. This material, also known as a super-absorbent polymer, which can absorb up to 150 x its weight in aqueous liquid.

This absorbent box to meet a liquid waste management problem. Several sectors are affected by this issue such as transport, catering, events and more.


The absorbent boxes designed by Recyc PHP are very simple. Just assemble a box used to contain the liquid. A plastic bag is inserted there to guarantee its sealing in which a water-soluble bag filled with sodium polyacrylate is there.

In contact with the liquid poured into the box, the bag dissolves and releases the sodium polyacrylate, which absorbs the liquid in contact with the material, and that until the box is filled with liquid. Thus, the liquid waste is converted into solid waste (in the form of jelly). Afterwards, users simply attach the filled bag and discard.

Utilisation Examples

  • Liquid waste management when the sewer system is not accessible (in festivals, transport)
  • Management of hazardous aqueous liquids in laboratories (contact us to ensure the compatibility of liquids with sodium polyacrylate)
