Ergonomical and efficient bigbag filling line
Bascules Robbe has installed a bigbag filling line and 14 sampling stations at Valomet in Ghent, a daughter company of the famous garbage disposal company, Veolia. The customized systems contribute to the sustainable recovery of non-ferrous metals of bottom ash.
We installed a bigbag filling line and 14 sampling stations at Valomet in Ghent, a daughter company of the famous garbage disposal company, Veolia. The customized systems contribute to the sustainable recovery of non-ferrous metals of bottom ash. With more than 1,900 employees and 45 locations, Veolia is busy with the waste and materials management of thousands of customers. One of the spearheads of the global operation concern is regaining precious materials out of waste. Veolia also gets raw materials out of residual products. This way, the bulk material of the bottom ash, which remains after the burning of waste in power plants, is used for the construction of roads or the production of stackable building blocks.
Non-ferrous metals in fine residual fraction of the treated bottom ash can also be found in aluminium, copper, lead and zinc. That’s why Veolia developed a sustainable technology, so these non-ferrous metals could also be used in a circular economy. With the so-called Valomet process, a series of non-ferrous metals is devided with a particle size up to 20 mm and a purity from 75% up to 95% (dependent on the type of material) out of the treated bottom ash. These products can be re-used via smelting plants and refineries as new raw materials in the metal industry. In 2015, Veolia started a pilot plant which achieved a capacity of 1,300 ton of non-ferrous metals.
Valomet factory
In 2018, Veolia in Ghent built a new Valomet factory, with the support of the Flemish Government. Today it has a capacity of 12,000 ton per year. It is the first European factory for the recuperation of non-ferrous metals out of bottom ash. Therefore, it is a real example of an efficient ‘zero-waste’ solution. Moreover, the location at the port of Ghent means a minimal impact on the environment too.
Bigbag filling line
Veolia aims for sustainability in all of her projects. This also applies to the packages of non-ferrous metals. For the realisation of a bigbag filling line and a series of sampling stations, Valomet counted on Bascules Robbe. For this project, an optimal ergonomy and maximum production capacity were two important parameters. The customer chose a bigbag filling line with a roller conveyor and two operation positions, based on the ‘Apollo’ execution. This is a type of filling station, with which the section of the roller conveyor is adjustable in the height. This way, no telescopic deposit pipes are necessary.
Platform
The operator works on a custom platform. From this position, he can easily remove a pallet with empty bigbags. Subsequently, the operator hangs the loops of the bigbag in hooks. For this job, he leans forward, but he is supported in a secure and comfortable way, by means of a cushioned railing. In order to make it even more user-friendly, the hooks at the back move automatically forward. Hence, the loops can easily be hanged too. Subsequently, the operator places the filler hose of the bigbag on the static deposit pipe. With a single press on the button, the hooks at the back move back and the hose is clamped around the deposit pipe.
Filling process
Before the filling, the empty bigbag is blown automatically by means of a fan, in order to guarantee fillings without any problem. The non-ferrous metals are dosed in the hanging bigbags. During the filling of the bigbag, a section of the roller conveyor moves – with a pallet placed on it – forward, in order to support the bigbag and to ensure stability. For the accurate dosing of the metal parts, Bascules Robbe has developed a special helmet visor. With this, every bigbag can be perfectly filled by weight. After the filling, the hose is automatically disconnected. Subsequently, the section lowers back in the roller conveyor. The pallet with full bigbags moves to the second work position, in which the bigbag is closed and labelled. All weights and other process data of the bigbag filling line are registered in a PLC which is connected to an operation system of Veolia.
Sampling stations
Bascules Robbe was responsible for the design and building of 14 sampling stations too. These are small bigbag filling units in which periodic samples of diverse types of materials from the production line are collected. Because of the low filling capacity, the bigbags are hanged manually in the sampling stations. The bigbag filling line and sampling stations are in accordance with all applicable standards and guidelines. Moreover, they meet the internal standards of the company Veolia.
