What is sludge ?

Sludge is a by-product of waste water treatment plants. Other recoverable by-products come directly from industrial processes (gypsum, concentrates, organic substrates, etc.).

Sludge and by-products are rich in fertilizing substances and can therefore be beneficial to agriculture. Their different origins make it possible to constitute a range of soil improver or organic fertilizers.
