Experiment & Piloting Activities

Since its inception in 1995 as a research and development organization, Waste Concern has been involved in the experiment and piloting of appropriate technologies for the waste and sanitation sectors. Over the last twenty three years, Waste Concern has developed and disseminated the following technologies suitable for Bangladesh and similar economies in the Asia Pacific region:

Developed ‘box type’ composting method with passive and forced aeration system
Developed low cost solution for ‘composting’ process in rural areas
Developed low cost ‘Trickling filter’ method for the treatment of leachate/ percolates generated from the following: faecal sludge and slurry from septic tanks, pit latrines, and biogas digesters
Developed co-composting method for treatment of dewatered sludge and municipal organic waste
Developed barrel type composting method for slums and low income settlements
Conducted research and experiments on production of ‘bio fuel’ from used cooking oil
Conducted research and operated ‘solar irrigation’ for agriculture
Conducted research on ‘biogas to electricity’ from different types of municipal waste feedstock
Conducted research on ‘biogas production and electricity generation from co-fermentation’ of municipal waste with faecal sludge
Conducted research and field trials regarding ‘application of compost in different crops’
Developed appropriate technologies for ‘grey and black water treatment system’ for communities and institutions as well as small towns
Developed decentralized waste water treatment systems for low income settlements
Developed integrated landfill and resource recovery facility for secondary and coastal towns
Developed method for ‘large scale composting’ facility with low land foot print
Developed “methodology to account for emission reductions from composting of municipal solid waste” which is approved by UNCCC
Developed methodology for quantifying co-benefits from recycling of municipal organic waste
Conducted research on ‘used lead acid battery recycling’ in Bangladesh
Conducted research and piloted ‘eco-toilets’ in Bangladesh; and
Conducted research on ‘soiled plastic waste recycling’

Through the research and development services provided by Waste Concern, governments, municipalities, communities, and private enterprises have made financial gains as well as contributed towards reduction of environmental pollution and its associated health and occupational risks.

Current Research Areas

Conducting research, development, and implementation of ‘large scale waste to energy’ facility using Anaerobic  Digestion Technology with high biogas production and low land foot print
Conducting research and experiments on ‘refuse derived fuel (RDF)’ from municipal waste
Conducting research and experiment on diesel production from single use plastic waste
Designing low cost sanitation systems for integration of non-networked sanitation system with networked system for low income and hard to access areas
