Recovery and treatment
COLLECTING, SORTING AND RECOVERING organic WASTE
SUEZ provides the public sector, companies and industrial sites with collection, sorting or recovery operations:
- specific collections for organic waste that can be recovered and returned to the soil
- mechanical-biological treatment to separate the packaging from recoverable materials for household waste not sorted at source
- bio-deconditioning of non-consumable food products
- transformation then sale of organic waste as compost on specialist sites
- recovery as heat
The group has gained expertise in the transformation of paper, plastic, metal and wood as well as hazardous waste and complex products:
- The waste recovery of secondary resources is applied in the manufacture of new products (plastic bottles and bags, cardboard for paper materials, preparation of metals, rubber-based granulates).
- Treatment and recovery of hazardous products (extraction of recoverable material, contaminated fuels and UEVH, contaminated packing, production of CCS/CLS fuels, etc.).
- Recovery of polluted land as a result of construction projects or industrial sites that are pre-treated on site (sifting, sorting, crushing, and dewatering in the case of sediments).
TRANSFORMING WASTE INTO ENERGY
The Group sets ups energy recovery facilities that generate electricity, heat or steam that could be used to power urban heating networks or be directly reintroduced into industrial processes. Waste can be transformed into energy-producing combustibles via a number of different processes:
- The incineration of non-hazardous waste generates electricity and/or heat from hazardous waste in furnaces generating energy in the form of industrial steam.
- Co-incineration where hazardous waste is treated to obtain alternative, liquid or solid fuels (CLS and CSS) with a high calorific value.
- Methanisation or biogas resulting from the fermentation of organic waste to power various recovery systems (motos or turbines) that generate power.
STABILISING AND STORING NON-RECOVERABLE WASTE
The group provides the implementation and operation of non-hazardous and hazardous waste landfill facilities.
Non-hazardous waste is contained in particularly well-equipped areas (wells) from where they are collected and then treated (leachings, for example, are sent to sewage treatment plants).
In turn, hazardous waste is stabilised via an industrial treatment procedure which, among other things, neutralises pollutants, before being stored in the site’s wells.
