Is HDPE can be used for storagge house?5 answersHDPE can be used for storage houses due to its favorable properties. HDPE/clay nanocomposites have been prepared and investigated for their morphological, thermal, and mechanical properties. The addition of nanoclay enhances the storage and loss moduli of HDPE nanocomposites. HDPE pipes, both recycled and virgin, have been evaluated for their chemical, morphological structure, and thermomechanical properties under UV exposure. The addition of carbon black, antioxidants, and UV stabilizers prevents pipe degradation during UV exposure. Recycled HDPE has been tested for its compressive creep behavior and found to have a creep rate of less than 1% in 100 years when loaded at an ultimate stress of 6.9 MPa. Cold-drawn polyethylene materials have been studied for their morphological changes and orthorhombic crystallinity decrease. The cold-drawn structure of HDPE can be annealed to recover its crystalline phase.
How can electronic and plastic waste-based materials be effectively utilized as sustainable alternatives in roofing?4 answersElectronic and plastic waste-based materials can be effectively utilized as sustainable alternatives in roofing. One approach is the use of non-bituminous binders made from bio-based rosin esters, waste cooking oil, and recycled polyethylene, which have shown suitable mechanical properties for roofing materials and enhanced energy efficiency. Another method involves the utilization of waste from the production of synthetic rubbers and various clays to develop composite materials for roofing. These materials have been shown to have high physical, mechanical, and operational properties, although crack resistance may be low. Additionally, a composite material made with recycled rubber from tires and recycled polyethylene has been developed for roof tiles. These tiles have high resistance to flexion, low thermal conductivity, and low water absorption, making them a sustainable alternative for housing covering. Furthermore, the use of construction and demolition waste in green roofs has been explored. While C&D waste reduces water retention performance compared to plastics, it improves runoff water quality.
