城市固體廢物管理已成為全球關(guān)注的焦點,影響到全球的各個的國家,特別是受影響最嚴重的發(fā)展中國家。大多數(shù)國家的經(jīng)濟發(fā)展、城市化、人口增長和大規(guī)模工業(yè)化產(chǎn)生的廢物逐漸增加。然而,隨著世界的發(fā)展,固體廢物的增加預計會比想象中的更快。因此,各國有必要探索有效的廢物管理措施,因為管理不善的廢物會影響到社會發(fā)展,如:生態(tài)環(huán)境、人類健康等。城市固體廢物中含有有機成分的溫室氣體排放已經(jīng)影響到全球環(huán)境。雖然,發(fā)達國家有符合國際標準的有效廢物處置工具和政策;但,大多數(shù)發(fā)展中國家,固體廢物的收集、分類、運輸、處理和處置都存在問題。目前,可持續(xù)的廢物管理把重點放在廢物來源減少,再利用,并通過熱應用回收,而不是單純的廢物收集和傾倒或填埋。例如,3Rs原則的有效應用,形成了良好的廢物管理的基礎,減少廢物產(chǎn)生的甲烷、二氧化碳等,從而減少環(huán)境中的溫室氣體,兩者的聯(lián)系錯綜復雜。因此,本論文探討了加納和中國的固體廢物問題和前景,兩個國家如何更好的相互借鑒廢物管理的優(yōu)勢,同時提供一個共同的合作平臺,以解決城市固體廢物面臨的挑戰(zhàn)。論文重點介紹了手工金礦(AGM),AGM給所涉社區(qū)帶來許多社會經(jīng)濟效益,但,其對環(huán)境也有很大的影響...
