  • the collected formulation is then separated into its respective types and stored in separate bins or storage compartments. If the formulation is of a quality that means it is suitable for re-use the formulation may be repackaged or simply stored for subsequent re-use. It is envisaged that such formulation will be re-used on community projects, such as mural painting or the like. It is estimated that up to 15% of the formulation collected will be of a quality such that it can be reused in its current state with no further processing in the likes of community based painting projects. It is envisaged that the recovery programme will link with community groups either directly or through local authority programmes to supply paint for reuse. One of the goals of the programme is to maximise the amount of paint that is recovered for community based purposes.

It is envisaged that solvent based formulation will be processed to recover the solvent.

  • the method may include the step of recycling any associated formulation containers. Where the containers are steel these are crushed, recycled and processed for subsequent steel recovery. Where the containers are of a plastics material these are recycled and processed for subsequent plastics recovery and reuse.

It is envisaged that this data will assist in making recycling decisions to optimise resource recovery.
  • the vehicle 1 illustrated in Figures 2 to 6 is a specialist vehicle set up for the purpose of mobile recovery of water based and solvent based formulations.
  • the rear body of the vehicle 1 includes a storage compartment 2 for storage of solvent based formulation and a storage compartment 3 for storage of water-based formulation.

  • the arrangement of storage compartments may be varied.
  • the storage compartments may be drums located on a carousel, which drums can be readily replaced as needed.
  • the vehicle preferably further includes an extraction or ventilation system (not shown) for the evacuation of paint fumes.
  • the vehicle preferably includes a lifting mechanism 8, such as a side lifter, fork lifter or tail lifter to enable the lifting of heavy loads into the vehicle.
  • a console 9 enables an operator of the vehicle or processing system to select whether the formulation is water based or solvent based formulation in a plastics or steel pail.
  • the pail and enclosed formulation is placed on the console area and the processing system 10 (see Figures 7 to 11 for the features of a processing system) is then activated by electronics (not shown) to deposit the pail and formulation into the crusher 13.

  • the formulations may be collected in large drums instead of fixed tanks.
  • drums would be held on a carousel underneath the crusher and can be selected by an operator by rotating the carousel so that the formulation drains into the appropriate drum. When full the drum can be sealed and then transferred from the carousel to a storage rack on the vehicle pending off-loading.
  • the associated crushed pails are then conveyed by a conveying means, such as an auger 14 or 15 depending on the nature of the packaging (shown in Figure 4), into storage compartment 4 or storage compartment 5.
  • the selected storage compartment again depends on whether the material is metal or plastic.
  • the storage compartments 4 and 5 each have a bund 16 and 17 respectively to capture and contain any residual formulation draining from storage compartments 4 and 5.
  • Auger discharge points 19 and 20 are also provided should formulation drain from the crushed packaging during conveyance into the storage compartments 4 and/or 5. It is to be appreciated that while twin augers 14 and 15 are illustrated, a single auger could also be used to transfer the crushed formulation packaging to the appropriate storage compartment.
  • the crusher is a cylindrical sleeve arrangement having a first outer sleeve and a second inner sleeve. A can is located in the first outer sleeve and drops into the inner sleeve when the aperture of the outer sleeve is aligned with the aperture of the inner sleeve.
  • the inner cylinder then revolves to enclose the can, which is then crushed by a ram with the formulation contents being squeezed out through one or more openings in the base of the cylindrical sleeve arrangement.
  • multiple cans can be loaded into the crusher for a crushing cycle.
  • the loading of cans into the outer cylinder can be either done directly or via a loading system which enables the cans to load continuously while the operator undertakes other tasks.
  • plastic pails which have waterbourne paint are preferably emptied by hand into a drum or tank and the residual paint can be cleaned from the pail using a revolving spigot and crown system that is preferably located in the truck adjacent to the crusher. The cleaned pails are then transferred to a compartment in the rear of the truck to be discharged when the packaging compartment is full.
  • the storage compartments in the vehicle that contain formulation are emptied by gravity or pumped into a larger holding tank and held for subsequent bulk processing.
  • the solvent based formulation is put into a larger solvent based holding tank, preferably for subsequent solvent removal.
  • the water based formulation is put into a larger water based holding tank.
  • the crushed metal may then be either stored or baled and passed onto a metal recycler for recycling.
  • the crushed plastics may be sent to a plastics recycling plant.
  • the vehicle be further equipped with safety features, such as side intrusion bars 18 (shown in Figure 4) to prevent rupture of the formulation storage compartments, a vapour extraction system and bund areas to contain any formulation spills.
  • the vehicle includes a tracking system to record details, such as the volume/weight of formulation picked up, the pick up location, any levies paid or owing and the like.
  • the tracking system may be incorporated into the console used by the vehicle operator so that the operator is prompted at the time of processing the formulation and any associated packaging to record key data.
  • a stand-alone processing system as illustrated in Figures 7 to 11 could be incorporated into any vehicle that could be used for a formulation recovery programme.
  • the processing system could be located in a designated formulation recovery site, such as a paint retail shop.
