Running out of land!

If the landfill solution is maintained, in the next five years, Ho Chi Minh City will no longer have landfill. Meanwhile pollution due to leachate, bad smell is getting worse .

Mr. Tran The Ngoc, director of Ho Chi Minh City Department of Natural Resources and Environment, said the Dong Thanh (Hoc Mon) garbage disposal site has closed the yard, did not receive solid waste but only received debris, about every day 900 tons. Meanwhile, in the first yard, Phuoc Hiep processing complex is receiving about 1,500 tons per day. The amount of leachate here is collected to 18 holes.

According to Mr. Ngoc, Go Cat garbage treatment area (Binh Tan district) receives 3,000-3,500 tons of garbage every day. The amount of leachate here is stored in two lakes about 60,000m ³ .

The Urban Environment Company had to reinforce and enhance the embankment so that there was no breakage and overflow of leachate. However, because the leachate treatment system is having trouble at the pre-treatment system before entering the nanofiltration system, the amount of leachate treated every day . only reaches 40m3.

To overcome the reduction of leachate load here, especially in the rainy season, Urban Environment Company must carry 700-800m3 of garbage water to Dong Thanh yard every day to handle.

Particularly in the landfill No. 1 (Cu Chi), due to incidents, measures must be taken such as reducing the reception capacity at the site from 3,000 tons / day to 1,000-1,200 tons / day; buried mainly on the top of the beach, then leveled to both sides, increased rain cover to reduce the density of garbage .

Still continue to bury

The amount of garbage is increasing. In 2006, the volume of waste increased more than in 2005, of which domestic waste increased by nearly 8%, debris increased by 15%.

However, according to Mr. Tran The Ngoc, in 2007-2008, the city still had to continue burying garbage with VWS project (2,500 tons / day) and landfill 1A- Phuoc Hiep (3,000 tons / day).

In the period of 2009-2010, it is expected to reduce the amount of landfill to 35%, because at that time the city only had compost processing projects (accounting for 23%) and recycling classification (accounting for 14%) of six enterprises. participation. At this point, the project of burning waste into electricity at Da Phuoc is expected to process about 2,000 tons / day to form.

The leaders of the Department of Natural Resources and Environment of Ho Chi Minh City explained that in November 2006, the department received the projects of solid waste treatment projects and selected six projects in phase 2. The department will select two projects. feasible, which prioritizes the project of burning and recovering electric energy with the suggested processing price of 16-18 USD / ton, electricity selling price of 0.06-0.08 USD / kWh.

Criteria for approval include: technology, materials and equipment, environmental standards . In which priority is given to advanced technologies such as burning, making microbiological fertilizer in combination with collecting gas generation, or even more, as a complex that deals with many interconnected technologies, supporting each other.
