ALLU launches concrete bucket for on-site demolition processing

ALLU unveiled a new excavator attachment designed to crush and screen demolition concrete at the jobsite, aiming to cut hauling, improve workflow and recover more reusable aggregate. The launch targets contractors handling mixed demolition waste in space-constrained or high-volume projects.

Why it matters: - The ALLU Concrete Bucket lets contractors process demolition concrete where it is generated, which can reduce hauling costs, lower fuel use and improve material recovery. - On-site crushing and screening can also streamline demolition workflows in urban jobsites and other locations where space is limited. - The attachment is aimed at contractors trying to turn mixed demolition waste into reusable aggregate for recycling, backfilling and civil works.

What happened: - ALLU, a Finland-based manufacturer of material processing attachments, launched the ALLU Concrete Bucket on July 14, 2026. - The excavator attachment is designed to crush and screen pulverized demolition concrete directly at the point of demolition. - ALLU said the product is intended to help contractors process materials on-site instead of moving debris to a secondary crushing facility. - The launch was announced from Pennala, Päijät-Häme, Finland.

The details: - The Concrete Bucket is built for excavators in the 25- to 45-tonne operating class. - The attachment accepts feed material up to 300 millimeters, or 11 inches. - Finished aggregate output can be 0-50 millimeters or 0-100 millimeters, depending on the counter blade configuration. - Under suitable operating conditions, the attachment can process up to 100 tonnes of material per hour. - The unit is designed to handle pulverized demolition concrete, reinforced concrete, brick, asphalt fragments, demolition rubble and other mixed construction materials. - The attachment is engineered for reinforced concrete applications where steel contamination is common. - Reinforcing steel and rebar can pass through or be separated during processing, helping keep material flow moving. - The design uses rotating drums with replaceable carbide picks and a counter blade structure to crush and screen material continuously. - Replaceable wear components are meant to allow routine maintenance at the jobsite. - Compatible carriers can use ALLU’s Drain Line Eliminator hydraulic technology to simplify installation and improve operating efficiency.

Between the lines: - The launch reflects broader demand in construction and demolition for equipment that reduces handling while increasing the value of recovered materials. - ALLU is positioning the Concrete Bucket as a simpler alternative to moving debris off-site or adding separate processing machines. - Field testing with Ursa Demolition suggests the company is using real-world performance to validate the attachment’s production capacity and handling. - Jonathan Bjon, chief executive officer of Ursa Demolition, said the attachment has shown strong production capacity and handling characteristics in demolition applications. - ALLU’s leadership framed the product as part of a wider push to improve productivity and responsible resource management.

What's next: - Contractors using the Concrete Bucket can incorporate on-site crushing and screening into demolition projects as the attachment rolls out through ALLU’s channel. - The company is likely to lean on the product’s productivity and sustainability pitch as demand grows for reusable aggregate and lower-cost material handling. - ALLU said it will continue developing material processing solutions as project requirements evolve.

The bottom line: - ALLU’s new Concrete Bucket is designed to make demolition waste processing faster, cleaner and more local by turning an excavator into a mobile crushing and screening tool.
