Accumulating unmanaged palm oil wastes and quarry dust has resulted in an increasing environmental concern. Recycling of quarry dust and palm oil wastes like the palm oil fuel ash and the palm oil clinker as building materials appeared to be a viable solution to such a pollution problem and the problem of buildings' economic design. Therefore, this research is the first attempt to produce hybrid interlocking blocks from palm oil waste and quarry dust. Hybrid interlocking blocks (HIB) were produced by mixing palm oil fuel ash, palm oil clinker, palm oil clinker powder, and quarry dust with merely 10% cement by various constitutes. The production methodology using proposed new mix design, neither exhausted the virgin material of earth nor consumed energy resources or emitted contamination, with significant economic and ecological benefits. HIB blocks were tested for engineering properties such as the density, compressive strength, ultrasonic pulse velocity (UPV), modulus of rupture, water absorption, a compressive strength of prisms, efflorescence, thermal conductivity, and leachability. Furthermore, the investigation on the durability of the blocks in laboratory accelerated tests and actual climatic exposure for 12 months also have been conducted. The hardened density ranged in 852.82 kg/m3 and 1561.21 kg/m3, and the compressive strength of the blocks ranged from5.01 MPa to 14.57 MPa, respectively. Meanwhile, UPV ranged in 1.25 km/s and 2.67 km/s. Furthermore, the modulus of rupture ranged between 0.69 MPa and 3.71 MPa; water absorption varied from 13.18% to 21.94%. The compressive strength of prisms ranged in 2.35 to 6.85 MPa, meanwhile, thermal conductivity filled in the range between 0.27 w/m k and 0.136 w/m k, respectively. Results for the leachability and the durability were rewarding and promising. The block's properties satisfied the relevant thresholds and were better than the properties of the conventional stabilized compressed The mix design proposed in this research, especially mix A''11, which considered as optimum mixture showed acceptable results in terms of the properties of the block. In conclusion, the blocks developed in this research can be classified as lightweight and thermally efficient. They can be used as substitutive to the conventional blocks in the building construction sector.
