VietNamNet Bridge – At a meeting held on the occasion of Vietnamese Women’s Day on October 20 in Hanoi, a delicate woman caught the special attention when she introduced herself as the inventor of a dishwashing and floor cleaning liquid made of plant waste.
She was Trinh Thi Hong, director of Minh Hong Biotechnology Company based in Da Nang.
Hong’s washing liquid is made after a special process. It needs 3 kilograms of plant waste to create 2 liters of finished liquid. The waste is cleaned (tree leaves, vegetables, flowers and fruits) and cut it into 3 cm pieces. It is mixed with 10 kilograms of water and 300 grams of sugar and put in in a closed bucket for 30 days.
