Gasification technology converts the solid and liquid waste materials into a usable synthesis gas through a chemical reaction
Renewable Energy Management Systems Bangladesh (REMS) has come up with the latest technology, known as gasification, to generate electricity from waste in the country.
Gasification was used successfully for the first time in 2018 in the US state of Kentucky to generate 40 megawatts (MW) of electricity from waste.
REMS, which aims to introduce the technology in Bangladesh, says it will help any power plant with the technical knowhow for the gasification process.
"We will generate electricity from waste in Bangladesh with the assistance of American technology innovator Green Planet Ecosystems LLC [GPE] in order to add renewable energy to the national grid," Zaman Tuhin, chief operating officer (COO) of REMS-Bangladesh, told Dhaka Tribune.
"There will not be any environmental risk. We are optimistic about getting all kinds of support from the government. Such renewable energy technology will also help reduce pollution," he added.
REMS-BD provides technical support in diverse fields of intelligent solutions, power generation, oil, gas & energy sector as well as manufacturing.
According to the US Environmental Protection Agency (EPA), 700 crore people of the world produce 181.30 crore tons of waste annually. Of those, 8% are reusable and the rest cause damage to nature, putting people's health at risk as well.
Waste management scenario of Bangladesh
With only six important cities in the country generating 8,000 tons of waste per day, Bangladesh still lags far behind in waste management.
In addition, medical waste, particularly now the Covid-19 waste, is posing a serious threat to the health management of the country.
In waste management, Bangladesh is still working on principles of landfill and incineration.
However, the upper echelons of the government have been talking for several years on if there is any safe technology to meet the demand in Bangladesh's power sector from waste.
Zaman Tuhin said: "Bangladesh has not yet seen effective steps in this initiative to generate electricity from waste. Arguments and suggestions are also being made about whether the technologies that are still being talked about, are causing new environmental pollution or not. In the overall situation, Bangladesh has not yet come to a timely, sustainable and constructive decision on which technology should be used."
Is gasification technology a solution?
Gasification technology converts the solid and liquid waste materials into usable synthesis gas, or syngas through a chemical reaction. It is a unique process that transforms a carbon-based material into other forms of energy without actually burning it.
The first success was recorded in Kentucky, USA. Later, many countries have shown their interest to use the technology. India, Ghana, South Korea, and Thailand have already planned to deal with the Green Planet Ecosystems LLC (GPE) for generating electricity from waste.
Zaman Tuhin said: "We will also use the new technology known as gasification solution.
"The most effective aspect of this technology is that it converts any type of waste, including medical waste, directly into a special gas [syngas]. In this way, the effect of medical waste on the environment can be completely suppressed.
"We are the first partner to introduce this technology in Bangladesh," he added.
