The contractor is utilising a crusher bucket on an excavator to ensure that rubble can become a reusable aggregate ready for the next pour or fill. In Matera, Italy, this approach has been put to the test on a large-scale urban regeneration project linking the city’s historic centre with its modern district, redesigning an area of 3.8ha. A new park is being built in the centre of Matera, but the need for transport is not being overlooked as an underground parking area forms a key part of the work. New drainage with improved rainwater control and adaptive LED lighting also form part of the work.
The project is being carried out under the guidance of engineer Carla La Torre from Trezza. The team behind the project chose to crush and recycle onsite. The firm’s Doosan excavator was fitted with an MB Crusher BF90.3 which transformed demolition and excavation debris into valuable material used immediately for landscaping, base layers, and subgrade fills.
On a large construction site, the MB Crusher jaw crusher allows materials to be crushed directly at the working area, without the need for trucks for internal transport. According to BM Crusher, users of the units can crush material where demolition occurs and reuse it immediately, such as sub-base for new roads, saving significantly on logistics, material costs, and time. As the crusher bucket is mounted on the excavator, it goes wherever the machine is moved at the working site. This reduces construction site traffic, waiting times, and pollution
By cutting out landfill trips and reducing truck traffic, the site has seen faster progress, cleaner operations, and significant cost savings. Removing the cost of landfill charges by reusing the material instead has made a major benefit for the overall pricetag for the project, while also helping reduce the carbon profile for the contractor.
The recycling work is also efficient and productive and the integrated 24V magnetic separator ensures that steel is removed safely without interrupting the crushing flow, which is important for optimising efficiency and safety. The device is controlled from the excavator cab, ensuring complete safety for both the operator and the construction site.
