Received: June 06, 2017 Revised: July 05, 2017 Accepted: July 19, 2017 Abstract: Introduction: The use of polymer wastes in pavement as road is an increasing trend in the road construction sector. Those new pavements reduce the amount of solid waste disposed into landfills and provide more sustainable construction due to the use of in-situ materials. Polyurethane foam waste is a thermostable po...

It is argued that the flow process analysis essentially provides two new options for improvement of production: elimination or reduction of non value adding activities (also called waste) in flow processes and increase of output value from the customer point of view. The typical categories of waste and value loss in a construction project are analyzed in this framework, and the corresponding im...

The Korean government has strived to secure a disposal site for the safe management of radioactive waste since the early 1980s. The 249 th meeting of the Atomic Energy Commission (AEC) held in September 1998 established the “National Radioactive Waste Management Policy”, which aims at completing the construction of a Low and Intermediate Level Radioactive Waste (LILW) disposal facility by 2008,...

Waste minimization and recycling are principles of the concept of sustainable development that is now globally introduced. Construction in the sense of manufacturing goods and construction and exploitation of buildings generates a significant amount of waste. Therefore, the developing of the concept of waste management and the reverse logistics is implemented to the construction industry. A sta...

T. Lis, K. Nowacki, K. Łakomy Silesian University of Technology, Department of Production Engineering, Katowice, Poland In the European Union one of the most important activities is the recovery and recycling of waste including foundry waste. In the article waste arising from production of iron casting was presented. Selected physic-chemical properties of iron-bearing waste were defined. Opport...

Conventional leaching (extraction) methods for gold recovery from electronic waste involve the use of strong acids and pose considerable threat to the environment. The alternative use of bioleaching microbes for gold recovery is non-pollutive and relies on the secretion of a lixiviant or (bio)chemical such as cyanide for extraction of gold from electronic waste. However, widespread industrial u...

The current waste management literature lacks a comprehensive LCA of the recycling of construction materials that considers both process and supply chain-related impacts as a whole. Furthermore, an optimization-based decision support framework has not been also addressed in any work, which provides a quantifiable understanding about the potential savings and implications associated with recycli...

The major decision in construction process involves the selection of suitable site with best soil conditions, as structure resides in the soil. Most problematic soils like expansive soils hardly proved to be the best engineering subgrade profile for pavement constructions. Thus, this has undeniably led to the soil improvement options accompanying the reduction in resource depletion and solid wa...
