Green360 Technologies has penned an agreement to produce low-carbon retaining wall blocks in a joint venture with leading Western Australian precast concrete manufacturer PERMAcast.
The companies’ 50:50 joint venture will produce and sell low-carbon retaining wall blocks to WA’s hungry mining construction market, as well as the residential, infrastructure and commercial sectors.
Under the non-binding memorandum of understanding (MoU), PERMAcast will fund the acquisition of a specialised block-laying machine and a concrete batching plant, enabling the production of 1-metre-long low-carbon retaining wall blocks for net-zero or ESG compliant construction ventures.
The joint venture entity will have exclusive rights to purchase the blocks at cost from PERMAcast and on-sell them, with all profits shared equally between the partners.
Green360 says the agreement promises significant revenue and cash flow opportunities and will fast-track commercialisation of its new-world technology.
The company’s proprietary cement formulations use industrial by-products to ensure the blocks have a lower embodied carbon footprint compared to traditional concrete products.
The in-house production model allows for precise control over mix designs, ensuring compliance with strict performance and sustainability standards, including net-zero and ESG targets increasingly demanded by major projects.
The blocks are expected to be the joint venture’s first low-carbon product sold in commercial volumes, with production equipment slated for commissioning at PERMAcast’s facilities by mid-next year, pending final agreements.
As WA’s construction sector experiences a mining-induced boom cycle, giants such as BHP and Rio Tinto are bleeding the construction industry dry of supply in pursuit of port expansions, infrastructure and residential projects.
Green360 says its 1m blocks are in high demand for these applications, including main roads, flood and erosion control infrastructure, mining camps and camp expansions.
By producing the blocks in-house, the joint venture says it can tailor products to meet specific project needs - whether to meet strength, durability or environmental criteria - while maintaining cost efficiency and rapid scalability.
Green360 Technologies executive chairman Aaron Banks said: “We’re excited to take this step with PERMAcast toward bringing low carbon retaining wall blocks to Western Australia - a region undergoing rapid growth in urban development, infrastructure and resource-driven construction. The 1000 x 350 x 350 format is widely used across the state for retaining walls, earthworks, road corridors, mining camps and port upgrades - making it a high-volume, high-impact opportunity to demonstrate our low carbon credentials.”
The Australian concrete market is projected to reach $2.6 billion by 2033, fuelled by urbanisation and a push for sustainable construction practices, according to industry analysis from IMARC Group. However, a clear supply deficit for large-format retaining wall blocks, particularly those aligned with carbon reduction goals, has created a prime opportunity for Green360 and PERMAcast to capture market share.
The non-binding MoU exploits an immediate market gap on a global push to decarbonise the cement industry, which accounts for up to 8 per cent of global carbon dioxide emissions. By leveraging PERMAcast’s established infrastructure and Green360’s innovative cement technology, the joint venture can capture market share as an early mover in the specialised industry segment.
While the MoU is non-binding and subject to final agreements, the partnership builds on a clear market need and a reputable partner in PERMAcast. Green360 is cementing its position as a leader in sustainable construction materials, ready to disrupt a rapidly growth low-carbon cement market with its flexible and sustainable solutions.
