Non-governmental organisations (NGOs) may enter into SWM related activities for a number of motives—social concerns for waste pickers, introducing new recycling technology (e.g. composting), extending micro-credit, concern for the poor environment in which their beneficiaries live, or simply because they are contracted by other agencies to implement a project. They are driven mainly by the need to achieve their goal, and not to make profit. Their scope of work may include primary collection, rehabilitation of waste pickers, building awareness in the communities, dissemination of information, research and the introduction of new technology. NGOs traditionally work closely with communities and there is usually good co- operation from the community members. Sustainability of NGO initiated operations depends on the length of their ‘interest’ in the project or on external source of funding. However, sometimes the initiatives may be picked up by entrepreneurs and developed into self-sustaining enterprises
