China-headed biomass combustion technology providers DP CleanTech Group has announced that it has recently signed a contract to deliver a municipal solid waste (MSW) to biogas solution to the city and municipality of Patuakhali, located in the southern coastal region of Bangladesh. In cooperation with Dhaka-based agro-industries service provider Chicks and Feeds Ltd, the project will produce biogas of approximately 10 000 Nm3 per day and 60 tonnes per day of compost.
Patuakhali is one of the oldest municipalities in Bangladesh and has all the characteristics of a rapidly growing urban, industrial area. Huge population growth and increasing levels of consumption have led to spiraling levels of municipal and industrial waste, and the waste management system has not been able to keep pace.
The low lying area is bounded by three rivers and is also prone to flooding, which further exacerbates the problems of contamination and odour. Public health issues caused by environmental degradation and poor waste management are serious concerns for the local community and municipality leaders.
A number of small-scale projects are operating to try and address the waste problem, but the projects lack coordination and focus primarily on the mechanics of waste collection and (often uncontrolled) open landfill dumping. The emphasis is slowly turning to more sustainable waste management projects.
DP CleanTech has worked on numerous projects in similar environments, designing and installing waste sorting and biogas conversion technologies that are well-proven, reliable, and maintenance-friendly.
For this project, the value of which has not been disclosed, MSW treatment plant will use a dry anaerobic digestion system developed by the company using 100 tonnes-per-day of primarily organic, pre-sorted MSW.
The biogas will be upgraded to vehicle grade biomethane and food-grade quality carbon dioxide (CO2) by the project owner.
