A young civil engineer in Gaza has been recognised internationally for inventing a concrete building block made from recycled rubble and ash, which makes the blockaded territory less reliant on imported aggregate and cement as it struggles to rebuild.
New UBCO research suggests recycled concrete could be a sustainable way to keep rubble out of landfills By Nathan Skolski on November 30, 2020 Shahria Alam, co-director of UBC’s Green Construction Research and Training Centre and the lead investigator of the study.

Recycled aggregate: The time is now. Lock-Block Ltd. annually processes over 300,000 tonnes of concrete rubble from construction sites into high-quality aggregates suitable for making fresh concrete. That’s thousands of tonnes diverted annually from landfill sites, and made into useable products that we sell under the Green-Stone brand.
Composite ICF / ICCF “blocks or forms” like The Perfect Block are a green building product made of a mixture of recycled expanded polystyrene EPS commonly known as “Styrofoam”, Portland cement, and proprietary admixtures and water. 100% of the EPS used in our form is recycled EPS.
We utilize these recycled materials to help divert as much waste as possible from the landfill and to create new Pole Base products. Going Green By recycling concrete and demolition materials, we keep heavy, non-compactable rubble out of the waste stream and reduce airspace in the landfill, which saves money and natural resources.
Blocks are assembled through dry vertical interlocking and thin-mortar horizontal jointing. Manufacturer Ibstock/ZWK Supplier Natural Building Technologies Component materials Clay, recycled paper, recycled PU bead Density 650kg/m3 Loadbearing strength 7N/mm² Thermal conductivity 0.09W/mK Thicknesses of block 300, 365, 425mm
Fortunately, concrete can be recycled and reused in many ways. Typically but not always the process involves crushing or pulverizing the concrete rubble near the demolition or building site. Choosing the best method often depends on the size and shape of the concrete pieces to be recycled.
