As known that the construction processes consumes a lot of raw materials and generates huge amounts of waste, which are transferred to public landfills, making them harmful to the environment, and this significantly increases the costs used to dispose them off. Therefore, it is necessary to look for better construction methods that contribute to minimizing waste resulting from construction work and thus maintaining a clean and healthy environment. From this point of view, many questions arise about the most feasible and applicable methods to reduce this waste. In our study, the tendency was to focus on the various stages of construction that result in this waste in construction sites. As it is known, the construction process goes through several stages, including planning, design, supply, procurement, construction and implementation stage. Thus, methods were devised from those stages and evaluated in terms of implementation cost and difficulty of implementation through conducting a field survey (questionnaire) for many public and private companies working in contracting and construction within the Green Mountain region and Benghazi. The aim was to obtain the general opinion of the respondents and evaluate it statistically to know the extent of its application in terms of cost and difficulty of implementation. The result of the inferential questionnaire of a rather small sample concluded that the inventory management and procurement management in particular almost kept their order in the two axes, and this is an indication of their importance in reducing construction waste. Also, the method of pouring concrete in suitable weather conditions obtains the first rank from the direction of the sample in the second axis and the second rank in the first axis with a percentage of 75% & 70%, respectively, as it is easy to implement and has low cost. In general, it is clear that about 60% of the sample members answered that the topic of the two axes and what they contain tend to be of average cost and difficulty of implementation. We recommend that the sample size be expanded to obtain more accurate results. Key words: Construction waste, Contracting companies, Inventory management, Difficulty of implementation.
