Enzymes from Invasive Weed Show Promise for Bio Cement Production

Researchers from the University of South Australia reported that enzymes from an invasive weed known as paddy melon could be used for developing bio cement. This discovery shows potential for the construction, mining, and forestry industries.

The researchers evaluated 50 native plants and weeds to look for cheaper and more eco-friendly sources of urease enzymes for bulk production. Of all the weeds evaluated, the paddy melon showed the greatest promise, showing characteristics similar to enzymes from soybeans, which are a more expensive source and commonly used for food.

“Compared to the production of commercial enzymes, paddy melon enzymes are cheaper, more sustainable, and more efficient than other enzymes used to cement and stabilize soils,” said Professor Mizanur Rahman.

Aside from being a good substitute for commercial enzymes, harvesting paddy melon for such use will also solve the problem of the agriculture industry with these invasive weeds. Furthermore, the same enzymes from the paddy melon could be used to secure tailing dams by forming a natural protective layer that traps harmful waste material and prevents it from leaking. This offers a more sustainable and potentially cheaper alternative to traditional methods.
