I am excited about the prime minister’s assurances that Thimphu will be one of the cleanest cities in the world by 2011. But I am not excited about how he plans to do it.
It appears that the government has decided to buy a waste incinerator capable of burning 40 tonnes of waste at a time. It should reconsider its decision.
Incinerators must burn continuously. So they require a constant supply of garbage. And the bigger the incinerator, the larger will be the amount of garbage needed to keep it running. As a result, we may need to produce more, not less garbage. This is not good waste management.
Incinerators pollute. The pollution will spread throughout our country and to our neighboring countries. Plus the smoke, gas and ash produced by incinerators contain dioxins that can cause cancer. This is not responsible.
Incinerators are expensive. In 2004, THPA paid Nu 4 million for a 2.4 tonne incinerator. Guess how much a 40 tonne incinerator would cost? Upwards of Nu 600 million! This, it seems, is what representatives of a Malaysian firm told the government when they visited Bhutan earlier this year to market their product. This is not cheap.
A much more simple, responsible and cheaper solution to our waste problem is to recycle it.
A businessman has already proposed to establish a recycling plant. This is his plan: he collects waste that has been sorted, washes and compresses it, and sells it as raw material to companies – in Bhutan or abroad – who manufacture products from recycled material.
Who sorts the garbage? That’s the catch – we, the producers of garbage do. Waste must be sorted at the source before it can be used by the recycler. But the good news is that Thimphu’s residents are willing to do so. At least, this was the experience in the mid-1990’s when NEC briefly tried a recycling project. Sorting our own waste teaches us to reduce consumption, reuse packaging and recycle – the all important 3R’s of waste management. Sorting our waste also teaches us to respect the environment. That’s GNH.
And there’s more good news: most of our garbage is recyclable, at least 70% of it is. That would mean that only 30% of our waste would need to go into landfills. And that would mean smaller, safer, cheaper and better-managed landfills would do for Thimphu.
How much would a recycling plant cost? About Nu 3 million. The government should finance the plant (donors are already willing) and subsidize its operating costs for the 10 years it would take before he can start turning a profit. In case you’re wondering, there’s a lot of money to be made from the sale of used plastics, glass, PET bottles and metals. Many companies use recyclable waste as raw material to produce finished goods. So the recycling plant would basically compact the waste so that it becomes easier and cheaper to transport.
It all seems so simple, doesn’t it? It is.
Yes, let’s make Thimphu the cleanest city in the world by 2011. But let’s do it responsibly.
