    Oxalor at Lezay : "A revolution"

    As a result of an idea launched in 1997, the Oxalor household waste treatment and valorization plant at Lezay, France, has been officially inaugurated on February 15th 2014.

The OXALOR® Process

Principle : a 100% natural, fully controlled and fast exothermic reaction

The OXALOR® technology is an innovative and industrialized  process for the treatment and valorization of raw household and assimilated waste.  The technology consists of  an attack of the organic fractions by a reagent called    « CALOX® » which is based on  Calcium Oxide (CaO)  : a well-known chemical principle optimized and redefined by the OXALOR® Group into a «high-tech» solution.

A 100% physico-chemical natural reaction allowing waste stabilizaton and sanitization

The incoming waste and materials undergo a fast (less than 3 hours) and natural exothermic reaction (approx. 90°C).  As a consequence, the treated outgoing waste is sanitized and dehydrated thus creating no odours nor lixiviats.   

Separation and Valorization

Four distinct fractions constitute the products issued from the treatment : 

  • A dehydrated and sanitized degraded organic fraction allowing its agronomical valorization.
  • A sanitized non-organic fraction (PET, ferrous and non-ferrous materials)  allowing a valorization through the recycling industry. 
  •  An RDF fraction (refuse-derived fuel) allowing "waste-to-energy" valorization.
  •  An inert fraction (which is neither chemically or biologically reactive and will not decompose) is destined to be landfilled.  This concerns only a small part of the treated waste (5 to 10%).
