Recycling is a key factor for economic benefits, health protection, and environmental resources conversation. This research aimed at assessing the current operational procedures of ZF-SLF, the effect of recycling and reusing of SW on ZF-SLF performance in terms of its expected service life and associated environmental impacts. The research also investigated incineration of wastes as an alternative for wastes landfilling.

Previous studies and available data related to Solid Waste Management in the study area (Northern governorates of the West Bank) were collected, and reviewed.

 In addition to current used procedure at ZF-SLF (Scenario I), four other scenarios were analyzed:

2. Recovery of certain materials through a material reclamation facility (MRF), and Landfilling of the rest. In this scenario, paper and cardboard, metal, glass and plastic wastes are considered to be partially separated and recycled. Organic wastes, textiles and other wastes to be landfilled.
3. MRF, composting plants, and landfilling. The same as second scenario but organic waste to be composted.
4. Incineration of all wastes excluding metals: metals will be separated and recycled.
5. Incineration, MRF, composting and landfilling: in this scenario, paper and cardboard, glass and plastic and textiles to be incinerated. Metals are to be separated and recycled while 75% of organics are to composted and 25% of organic to be landfilled.

Quantification of Solid Waste for each scenario was conducted and projected till year 2040. Mass-volume calculations were used to predict the expected service life of the landfill under each scenario assuming January 1^st, 2015 as a start date.

Environmental assessment was conducted based on life cycle assessment methodology considering year 2015 data and based on CML-IA baseline method V 3.02 method. Under CML-IA baseline method, scenarios were compared for each other in terms 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 and second stage will reach to their ultimate capacities by the end of year 2015 and 2020 respectively under (Scenario I), 2015 and 2023 under (scenario II),  2018 and 2034 under (scenario III),  2020 and 2039 under (Scenario V).

Also, the research showed that Scenario III (landfilling, MRF, and 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 terms of human toxicity, terrestrial ecotoxicity and acidification. Scenario IV (incineration of all waste excluding metals) had the highest gains in term of abiotic depletion but it had the highest adverse impacts in term of all rest categories.

Recommendations of the research are mainly to adopt recycling and composting of MSW in ZF-SLF and updating of the NSSWM to determine the recycling implementation tools. LCA should be adopted by decision makers to decide the optimal SWM options and policies to be used. Inventory data should be prepared at the national level, and this requires the cooperation of all governmental, private sector and researches agencies concerned about the SWM field. Also, the research recommends carrying out cost-benefit analysis for all scenarios.  Finally, Separation at source for organic waste is strongly recommended.
