Feasibility of waste recycling at landfill site: zahret alfinjan as a case study
Publication Type
Conference Paper

Recycling of solid waste is the major reason behind considering waste as resource. Recycling and sorting activities are limited at some locations in the West Bank. In the Zahret AlFinjan Sanitary Landfill (ZF-SLF), minor or nearly no recycling activities were practiced. This research aims at assessing the current operational procedures of ZF-SLF, and assessing the effect of recycling and reusing of SW on landfill’s performance in term of environmental impacts or benefits.

Several recycling scenarios were suggested. Life Cycle assessment (LCA) was used for assessing the environmental impact or benefits of each suggested scenario. LCA was carried out for the year 2015 based on CML-IA baseline method V 3.02 method. Under CML-IA baseline method, scenarios were compared for each other in term of seven environmental indicators; depletion of abiotic resources, Global warming, Ozone layer depletion, Human toxicity, Terrestrial ecotoxicity, Photochemical oxidation and Acidification.

Results showed that ZF-SLF first stage was supposed to reach its ultimate capacity by the end of year 2015 and the second stage will serve till year 2020 if all wastes are to be landfilled (Scenario I). Recycling (scenario II) will not affect the expected service life for the first stage of ZF-SLF but it will prolong the expected life of the second stage till year 2023. Recycling and composting (Scenario III) will prolong the expected service life of the second stage of ZF-SLF till year 2034.

Scenario IV, incineration of all wastes excluding metals (to be recycled) and organics (75% composting and 25% landfilling) will prolong the expected life for the second stage of ZF-SLF till year 2039. Also, the research showed that Scenario III (Landfilling + MRF + Composting) had the highest environmental gains in term of global warming, ozone layer depletion and photochemical oxidation. Minor differences in environmental gains are between scenario II and scenario III in term of human toxicity, terrestrial ecotoxicity and acidification. Scenario IV had the highest gains in term of abiotic depletion but it had the highest adverse impacts in term of all rest categories. Therfore, it is recommended that inventory data should be prepared at national level. This requires the cooperation of all governmental, private sector and researches agencies concerned in SWM field. Also, Cost-Benefit analysis for all scenarios is needed. Finally, Separation at source for organic waste is strongly recommended
