For quite some time Brussels Compost, jointly owned by the City of Brussels and Essent Milieu, had worked on developing a concept for indoor composting which would eliminate any odours leaking to the outside. If successful, this would eliminate their problem on the site in Vorst, and would also allow them to integrate odourless composting when assuming operational waste management assignments in other municipalities.
Important criteria when choosing a building was the resistance of the materials used against the harsh environment of composting. The Cover-All building concept met all requirements. The special steel structure, fabricated from ViperSteel®, with its additional coatings ensures the highest possible protection against corrosion. The special polyethylene fabric, Cover-All's exclusive DuraWeave®, provides for a unique, noncorrosive enclosure, with a high degree of light transfer. The high interior temperature of the compositing materials and the aggressive elements in the developing 'smoke' have little effect on the life expectancy of the building materials.
In the initial phase, a Cover-All TITAN® Series 3 was chosen with dimensions of 90' wide x 120' long (27.4m x 36.5m). The building is placed on a concrete ring foundation. Special provisions were made inside for the inlet and outlet of air. The extracted air is being led through a bio-filter, located next to the building. A large overhead door of 16' wide x 24.6' long (4.8m x 7.4m) allows for the passage of a shovel.
The building was erected in late 2005 and took 16 days for completion. Following the completion of the building, additional proprietary equipment was installed for the composting process after which the building was taken into operation.
