870,963 tones of pesticide contaminated soils in Nghe An & Ha Tinh are completely treated by Ecocycle Vietnam

 

On 30/11/2015, Ecocycle Vietnam processed 870,963 tonnes of pesticide contaminated soil stock in 02 provinces Nghe An and Ha Tinh. This is a part of the “Building Capacity to Eliminate Chemical Plant Protection; POP stockpiles in Vietnam” was what the the Project Management Board POP-Pesticide (Ministry of Natural Resources and Environment) and Chapter The UN Development in Vietnam deployed and controlled.

 

According to Department of Waste Management and Environment Promotion, there are about 1153 polluted spots caused by pesticides containing POP. Among these are various types of toxic pesticide which are difficult to be destroyed. Lacking of knowledge, local people stored pesticide in storages that did not meet the safety standards. From time to time, pesticides have started to absorb into storage floor and follow underground water leading to serious pollution in community.

 

In view of this severe issue, the Ministry of National Resources and Environment along with United Nation Development Program launched a bid seeking a contractor responsible for treating the most contaminated areas of Nghe An and Ha Tinh provinces. It was an international bid with participants from 14 different local as well as international firms.

870, 963 tons of pesticide contaminated soils in the districts of Vực Rồng, Thạch Lưu, Hòn Trơ, Chiến Thắng, Tân Phú and Nghĩa Đàn were collected and transported by Ecocycle to its plant in Hon Chong, Kien Giang province to co-process in cement kiln. Experts from the Ministry of Natural Resources and Environment and UNDP supervised the process.

 

Co-processing in cement kiln technology has been accredited as a safety and environmental friendly waste management solution thanks to its advantages: Extremely high temperature – up to 2,000°C, oxygen excess and long residence time destroy completely waste materials; no-residue after the process means no environmental risks compare with incinerator or landfill; high alkaline environment will absorb acid gases generated from the process, according to which, the effects on the environment from the acid gas will be eliminated; emission control system 24/24 in every Ecocycle plants ensures emission safety.

Throughout the process, relavant safety indicators have been strictly monitored and reported. Ecocycle particularly invited Pacific Environment – an Australian independent third party of environmental impact assessment to measure emissions in the process. The results showed that the treatment did not affect the emission. In fact, all emission indexes were much lower than the limit required, particularly, the concentration of HCl, CO, SO2, and NO were under the requirement limit, slightly dust emission comparing with the limits.

 

This project against pesticide residue contributes to the goal of “solving all areas of serious environmental pollution and particularly in 2025,” the government of Vietnam. The first ones to experience the difference are the people living in the contaminated area.
