Brick making is a major source of pollution and greenhouse gas emissions in Bangladesh. Amidst the country's expanding urbanisation, many construction projects use traditional bricks produced by burning topsoil from agricultural lands. This practice degrades arable land, threatening sustainable food production and aggravating deforestation. But with the help of the EU-funded SWITCH-Asia project SusBuild, 'alternative bricks', i.e. eco-friendly bricks that are non-burnt and do not require topsoil, are now becoming a reality in the industry.
