World over the air travel is the fastest growing source of greenhouse gases leading towards global climate change. Estimates show that each long distance flight of a 747 adds approximately 400 tons of CO₂ to the atmosphere. Like elsewhere in Libya too with the expected threefold increase in air travel over the next 30 years, the reliability and environmental impact of aviation are becoming critical issues for the future of flight in the country.

This paper is designed to present greener sky initiative indicating how Civil Aviation Technical College based at Sbia Libya in its march towards sustainable aviation is focusing on critical technologies like: (a) Integrated modeling of vehicles, atmospheric impact, and noise (b) optimization of new aircraft concepts and operations including environmental impact and (c) distributed, adaptive sensing and control. It treats sustainability is the way forward for aviation to …

Waste stream characteristics must be understood to tackle waste management problem in Tripoli

city, Libya. It is recognized that information on both quantity and composition of generation waste

is important for the effective planning of household waste handling infrastructure. So, this study is

aimed to evaluating the generation, composition and density of household solid waste in Tripoli

city, Libya. The study is carried out according to the Annex 2.1 of: WHO 1996. It was conducted

during one week in summer, autumn and winter 2011/2012. The daily household solid waste

generation assessment has been carried out for 150 Libyan families where 947 people in three

main parts of Tripoli city have been chosen randomly. A questionnaire was prepared according to

Buenrostro et al. 2001 and Raje et al. 2001 using door-to-door surveying. The result showed that

the average of total generation quantity, daily generation rate, total volume and density were

1415 kg, 0.64 kg/person/day, 19.3 m3 and 74.4 kg/m3 respectively in Tripoli city. Household solid

waste contains 36.3% organic matter and 32.5% recyclable materials (glass, paper, plastic, met-

als). The total generation quantity, daily generation rate, total volume and density were in Tripoli

city agreed with those for African and Arabic countries. But the problem is that Tripoli suffers

from insufficient municipal solid waste management and lack of sanitary landfills
