在泰国南部的三个示范区：关朗、Prik和Phattalung，已经对利用废物将养分回收到农业中进行了评估。采集了可生物降解固体废物和灰色废水的样品，并对其进行了理化特性分析。目前，可生物降解的固体废物和废水中的养分损失很大，特别是餐厨垃圾和灰色生活废水构成了很大的肥料潜力。家庭餐厨垃圾的人均日产生率分别为228g湿物质、0.65gN、0.16gP、0.34gK、0.05GS、0.39gCA、0.06gMG、6.9mgZn、0.29mgCu0.05mgNi、0.02mgPb0.09mgCd和0.006 mgHg。灰色生活污水的人均日产生率分别为：L 102gN、2.4gN、2.4gP、4.2gK、2.0GS、2.2GCA、0.82gMG、42mgZn、0.91mgCu1.6mgNi、0.46mgPb0.20mgCd、0.06mgHg。与常规化肥相比，废渣中K、Ca、镁、锌、铜、铅的含量普遍较高，而氮、S、镍、汞、镉的含量与常规化肥相当。
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. The average daily per capita generation rate of household kitchen waste is 228 g wet matter, 0.65 gN, 0.16 gP, 0.34 gK, 0.05 gS, 0.39 gCa, 0.06 gMg, 6.9 mgZn, 0.29 mgCu, 0.05 mgNi, 0.02 mgPb, 0.09 mgCd and 0.006 mgHg. The average daily per capita generation rate of grey household wastewater is 102 L, 2.4 gN, 2.4 gP, 4.2 gK, 2.0 gS, 2.2 gCa, 0.82 gMg, 42 mgZn, 0.91 mgCu, 1.6 mgNi, 0.46 mgPb, 0.20 mgCd and < 0.06 mgHg. The waste products generally contain higher amounts of K, Ca, Mg, Zn, Cu and Pb (relative to phosphorous) than conventional chemical fertiliser, while N, S, Ni, Hg and Cd is at the same level.
