Storage and pre-treatment

The chain of operations leading from the production of waste to its recovery or disposal is not a continuous chain; transition from one stage to the next, whether within the company, at the time of transport or outside the company, often requires storage. This storage notably allows the collection of waste by homogenous category and quantity, which contributes to optimising process costs. 2Storage within the company2 Waste storage within the company before disposal must comply with certain requirements. Solid ordinary waste should be stored in a waterproof and protected area to prevent it from being carried away by rainwater or the wind.

Liquid waste should be stored in watertight containers to avoid leakage. Retention tanks limit the risks associated with accidental runoff or incidents during transfer.

The choice of packaging equipment should be adapted to the duration of storage, handling conditions and transport.

Within an industrial zone, the grouping of companies enables better efficiency and savings in terms of waste storage and management. Selective waste collection common to all companies of the site carried out by a single provider contracted based on jointly established specifications generally guarantees the best economic conditions. This collection can also be combined with a corporate waste drop-off centre managed by the same provider.

For the deposit of toxic or hazardous substances and preparations, the following should be complied with:

Sorting this special industrial waste at source is compulsory, as treatment, disposal and recovery processes do not allow a mixture, which can often be hazardous. 2Non-hazardous waste transfer and sorting centres2 The distance between collection places and treatment facilities is sometimes significant; transfer centres are set up to reduce the nuisances and costs associated with transport and optimise the use of collection equipment.

Depending on the local recovery possibilities, sorting centres enhance the separation of recyclable household waste already subject to selective waste collection and/or company waste in order to produce homogenous batches matching the specifications of specialised companies. 2Main types of centres:2

The choice of the different platforms used is linked to the quantity and unit packaging of each type of waste collected, waste classification, potential hazard and logistical aspect of the collection:
