The establishment of industrial ecosystem is the key to realize the economical sustainable development. This article analyses the related literatures of industry ecosystem, and points out the industry ecosystem's hierarchy. Then on the basis of theoretical analysis, the article proposes the building strategy of the industry ecosystem, from three aspects of the microcosmic, the intermediate and ...

OBJECTIVE To determine the measures employers in the construction industry take to promote sustainable employability, the barriers and facilitators that influence implementation and employer needs. METHODS Questionnaire among 499 employers and interviews with 17 employers. RESULTS Employers expressed a need for alternative jobs for workers who can no longer perform physically demanding task...

Cement is one of the mostly used construction materials due to its high durability and low cost, but it suffers from brittle fracture and facile crack initiation. This article describes the use of naturally-derived renewable cellulose nanofibers (CNFs) to reinforce cement. The effects of CNFs on the mechanical properties, degree of hydration (DOH), and microstructure of cement pastes have been ...

The problem taken up in the study is the management of the company in terms of costs incurred on the implementation of the concept of sustainable development. The problem is important and topical in view of the possibility of increasing the efficiency of management in companies organizing their activities in the perspective of sustainable development. As a consequence of the formulated research...

Concrete is one of the most widely used construction materials in the world. However, the production of portland cement, an essential constituent of concrete, leads to the release of significant amount of CO2, a greenhouse gas; one ton of portland cement clinker production is said to creates approximately one ton of CO2 and other greenhouse gases (GHGs). Environmental issues are playing an impo...

a r t i c l e i n f o Green building rating systems Building performance analyses Today, there is a high level of demand for sustainable buildings. The most important decisions regarding a building's sustainable features are made during the design and preconstruction stages. Leadership in Energy and Environmental Design (LEED ®) is the most widely adopted sustainable building rating system in t...

An investigation was carried out to establish the physical, mechanical and chemical characteristics of a non-standard (unprocessed) pulverised fuel ash (PFA) and waste tyres from a former landfill site at the Power Station Hill near Church Village, South Wales, United Kingdom. Investigations are on-going to establish the suitability of the fly ash and/or tyres in road construction (embankment a...

We introduce the Maximum Sustainable Yield problem for a multi-robot foraging and construction system, inspired by the relationship between the natural resource growth and harvesting behaviors in an ecosystem. The resources spawn according to the logistic model and are vulnerable to overharvesting. The robots must maintain sustainability while maximizing productivity. The foraging robots harves...
