Indaver’s GFT digester, Bio Power Alphen, turned out to cause more of a problem with odour than was planned when it opened. Vicoma was asked whether the installation could be modified to minimise the environmental impact. An additional problem: there were hardly any drawings of the steel construction. A 3D scan provided the solution. A 3D scan provided the solution.
Project: odour nuisance from organic waste incinerator Bio Power Alphen
At the Alphen aan de Rijn site, Indaver processes organic waste materials into biogas and raw materials. The conveyor belts are closed from above. Nevertheless, a rather unpleasant odour was detected in the vicinity of the installation. This problem had to be solved. The odour nuisance had to be reduced to such an extent that it would no longer be a nuisance. It was Vicoma’s job to investigate the possibilities.
Vicoma’s role: realise solution to odour problem
To digitally map the current as-built situation Vicoma used a 3D scanner. Once the 3D scan of the complete outer structure had been made, check calculations were made of the new steel structure and the existing steel structure, concrete foundations and piles. Working in 3D also offers other advantages: a clash check, for example, to check whether the new adjustments did not interfere with the existing construction. To reach the solution to prevent the odour nuisance, Vicoma conducted three feasibility studies. Vicoma was also closely involved in the manufacturing, assembly and progress.
Result: adjustments lead to significant reduction of odour nuisance
Vicoma’s three feasibility studies led to the decision to install the conveyor belts locally and to install a new extraction system. This solution was supposed to significantly reduce odour nuisance. It has since become clear that the adjustments made have had the desired effect and there are no more complaints about odour nuisance.
