#1. Licensed Crusher Network in the UAE
Dubai: Dulsco Recycling, Bee'ah-affiliated facilities, and several private fixed crushers in Al Quoz and Jebel Ali. Abu Dhabi: Tadweer-licensed crushers in Mussafah and ICAD. Sharjah: Bee'ah's central crushing facility. All accept inert concrete demolition waste at AED 25–55 per tonne tipping fee.
#2. On-Site Mobile Crushing
Mobile jaw and impact crushers can be brought to large demolition sites (typically 8,000+ sqm or 5,000+ tonnes of concrete). Cost: AED 35–55 per tonne crushed including mobilisation. Savings vs hauling to a fixed crusher: AED 18–32 per tonne when haul distance exceeds 25 km.
#3. Recycled Concrete Aggregate (RCA) Specifications
Dubai Municipality and Abu Dhabi DMT permit RCA use for sub-base, fill, landscaping, and lower-grade structural concrete (typically up to C25). Higher-grade structural concrete still requires virgin aggregate. RCA classifications: Type 1 (sub-base, MOT compliant), Type 2 (fill), Type 3 (landscaping).
#4. Cost Savings Math
On a typical 5,000 tonne demolition (mid-size warehouse): landfill disposal AED 175,000–275,000 with haulage; on-site crushing AED 175,000–275,000 gross BUT the RCA produced has a market value of AED 30–55 per tonne (AED 150,000–275,000), reducing net disposal cost by 40–80% depending on local RCA demand.
#5. Circular Economy Mandates
Dubai Municipality Circular 188 sets a target of 75% C&D waste recycling by 2030, with progressive enforcement. Major government and Emaar/Aldar projects already require contractors to demonstrate >50% recycling. Tendering with a recycling plan is a competitive advantage.
#6. Quality Control & Contamination
RCA quality depends on contamination control during demolition. Wood, gypsum, plastic, and metal must be segregated before crushing or the output is downgraded. Best practice: segregated stockpiles on-site, magnetic separator on the crusher belt, and pre-crush manual picking.
#7. Practical Steps for Owners
(1) Specify in the demolition tender that concrete must be crushed and either reused on-site or delivered to a licensed crusher. (2) Require itemised tipping fee credits and RCA recovery accounting. (3) Where the project also requires sub-base or fill, specify RCA use in the new-works contract to close the loop.
