A pair of B.C. engineers have found a new purpose for plastic bottles in a place many would least expect: landfills.

Past researchers have found nearly a hundred metric tons of microplastics produced each year, with only a few getting recycled 害羞草研究所� making landfills one of the largest sources of plastic waste.

In response to this global issue, UBCO engineering professor Sumi Siddiqua has developed a way that can transform microplastic waste into stabilizing cover materials between the dirt and all that害羞草研究所檚 dropped in landfills.

害羞草研究所淒ue to its non-toxicity, low biodegradability and accessibility, it shows considerable potential for use in landfill designs. However, a considerable amount of research is still required,害羞草研究所� Siddiqua said in a statement.

害羞草研究所淭his not only solves the solid waste problem but also increases the economic value of waste and encourages its re-circulation back from already polluted lands and oceans.害羞草研究所�

Siddiqua害羞草研究所檚 recent research found that the reused material strengthens not only provides a layer of protection from harmful, polluting materials害羞草研究所� like lead害羞草研究所� from seeping into the soil and causing damage, but also can strengthen the dirt.

Doctoral student Alok Chandra, who works alongside Siddiqua, said this concept could also be integrated into geotechnical construction methods.

The study, which was published in the journal Waste Management, was funded by the Natural Sciences and Engineering Research Council of Canada Discovery grants program.

Chandra said he and Siddqua害羞草研究所檚 research into the possibilities of microplastics will continue.
