TREDI - HOMBOURG
INTRODUCTION
The Tredi Hombourg Centre was set up in 1974 to handle the treatment of waste effluents from some 150 metal surface treatment and electroplating plants in Eastern France. Today the centre is a major player in the elimination of hazardous industrial waste in greater eastern France.
Liquid effluents come to Tredi Hombourg from various metal treatment processes such as:
- Alkaline solutions from cleaning baths and phosphate tanks
- Acids containing heavy metals from pickling processes and iron perchloride
- Cyanide solutions from cleaning baths, zinc, copper and cadmium plating baths
- Regeneration of saturated mobile Ion-Exchanger resins
Tredi Hombourg has the capability to treat 36,000 tonnes of this waste per year. The incoming waste is identified and checked on reception, then treated by one of the following physico-chemical reactions:
- Oxidation of cyanides
- Reduction of hexavalent chromium
- Neutralization of acid or alkaline solutions
- Precipitation of heavy metals
Complimentary Services offered by Tredi Hombourg include:
- Collection and disposal of toxic wastes in small quantities
- Hazardous municipal waste
- Laboratory waste chemicals
- Agri-chemical and pesticides waste
- Assembling and repackaging of waste for disposal by deep burial eg.,cyanide or nitrate hardening salts, arsenic dust, etc.
Preliminary treatment and separation of wastes to be disposed of by high temperature incineration at other Tredi plants
The centre provides a wide range of additional services to industry; advice studies and analysis based on its government approved laboratory.
With the Hombourg Centre, Tredi meets regional needs, and at the same time has extended its range of activities. Incineration is one method of disposal, and is used today in four other Tredi Centres, but it is not suitable for all types of residue.
Another method is needed for inorganic wastes produced by regional industry.
This involves well-tried physicochemical reactions. Upstream from the industrial stage, wastes must be identified and extensive laboratory tests must be made in order to optimise subsequent treatment. This type of destruction requires know-how and technology, both for experiments and for operation.
The Hombourg Centre has always been a true innovator in this field, and was the first of its type to become operational in France.

The efficiency of the resins used in the exchangers is checked in the plants, and they are regenerated by the Hombourg Centre when necessary.

The Hombourg Centre thus provides a full range of services:
Physicochemical treatment: a job for specialists.
 Special Waste Packaging Unit
There are currently no satisfactory methods of detoxifying or destroying certain wastes, such as cyanide salts used for hardening metal, gas-scrubbing solutions containing arsenic, or activated charcoal contaminated with heavy metals. These wastes are prepared and packaged at the centre, and then buried deep underground, in disused mines specially prepared for the purpose.
 Disposal Unit for small quantities of Toxic Waste
Increasingly, local authorities, refuse-collection centres, schools, universities, laboratories, etc., ask the centre to identify and destroy small quantities of special wastes which are particularly harmful or dangerous, such as heavy metal salts, selenium and phosphorus. These toxic substances demand very careful treatment, by a process developed in TREDI HOMBOURG's officially-approved laboratory.
The know-know and facilities of the Hombourg Centre and of the other TREDI centres enable them to to meet this national need, particularly in the field of incineration
Preliminary Treatment
The Centre can also perform preliminary neutralising treatment, or, for example, eliminate heavy metals from organic effluents before transferring the latter to an incineration centre.
