SUCHADA P., J. TRÄNKLER, CHOLADA K. W. SCHÖLL. The role of formal and informal sectors in solid waste management of developing countries.   Proceedings Sardinia 2003, Ninth International Waste Management and Landfill Symposium S. Margherita di Pula, Cagliari, Italy; 6 - 10 October 2003 2003 by CISA, Environmental Sanitary Engineering Centre, Italy     Whilst in industrialized countries reasonable means are spent on refuse recycling and reclamation, this is practiced to a very efficient degree in the developing world. The formal and informal sectors play a major part in the recycling system of these countries. The complex recycling system of the formal (registered as tax payers) and informal sector of Phitsanulok, a city of 120,000 inhabitants in Thailand&#8217;s Central Plains, has been surveyed to assess its efficiency especially concerning the relief of the local landfill. The joint recycling activities account for 38% of the entire waste generation; therefore, the activities play an important role in the expansion of landfill lifetime. The quantities of recyclables collected and sold by the formal and informal sectors and other contributors sum-up to 19,200 tons/year. Sanitary landfill scavengers are of minor importance reducing the wastes before dumping around 0.6 %... The recycling activities comprise a comprehensive approach at great level of detail. Main fractions by weight are paper 36%, glass bottles 26%, and plastic container 9% and by value aluminum cans (3% weight).  The authors are members of the Asian Institute of Technology, Klong Luang, Pathumthani , Thailand or members of the Solid Waste Management Programme, Phitsanulok , Thailand.
