Datasets - Recycled LDPE
AI summary Read the abstract
This record is a dataset. Researchers in El Cercado, Dominican Republic, turned discarded plastic packaging (LDPE) into heat-pressed sheets used as lining for products like handbags and wallets. They tested how different processing times, temperatures and backing materials affected the material's strength and flexibility.
This study aims to address plastic pollution challenges faced in El Cercado, Dominican Republic, through a community-based approach. Discarded packaging sheets, films and wraps made of low-density polyethylene (LDPE) were heat-pressed into laminates, which were then used as lining materials for low-load consumer products such as handbags, purses and wallets. A full factorial design of experiments was employed, incorporating three input factors at two levels of variation each: processing time, processing temperature, and sheet metal backing material. Modulus of elasticity, ultimate tensile strength, elongation and yield stress were characterized to determine the impact of various processing conditions on the mechanical properties of the LDPE laminates.

Design of a methodology for the elaboration of ecological bricks incorporating low-density polyethylene
AI summary Read the abstract
Researchers in Mexico designed a methodology for producing ecological building bricks that incorporate low-density polyethylene (LDPE) plastic waste — the type found in plastic bags — which is very difficult to recycle through conventional means. The bricks met structural performance requirements while diverting plastic waste from landfills and the environment. Incorporating difficult-to-recycle plastics into construction materials offers a way to prevent them from fragmenting into microplastics in the environment.
