Availability and quality of solid waste and wastewater in Southern Thailand and its potential use as fertiliser.

Recycling nutrients to agriculture with waste in Southern Thailand has been assessed in three model-areas: Kuan Lang, Prik and Phattalung. Samples of biodegradable solid waste and gray wastewater were collected and characteris ed physically and chemically. At present nutrients in the biodegradable solid waste and wastewater are lost, but especially kitchen waste and grey household wastewater constitute a large fertiliser potential.

Composition of human excreta--a case study from Southern Thailand.

In Thailand, human excreta might be recycled into agricultural soils as a supplement to commercial fertiliser and thereby enrich the general fertility of the soils. However, for Thailand an adequate knowledge of the quality of human excreta, in order to assess its fertiliser potential, is not available. A literature survey revealed only very limited information of the chemical composition and generation rate of human excreta in South East Asia.
