“…Even though LCA is a technique designed to study environmental impacts, it can be very well connected to the LCC [41,42]. The LCC involves all costs associated with the life cycle of a product or service that are directly covered by one or more actors [43] and can follow the same four steps as the LCA with the aim of giving decision support. The literature distinguishes three LCC approaches, namely conventional LCC (CLCC), envi-consumption in relation to vehicle driving, loading or idling or in relation to manual labour with mechanistic modelling can give more accurate results [see e.g.…”

Modern environmental and economic challenges in waste management require transition from linear to circular economic flow. In practice, this entails considerable challenges that include the change of material circle flux, the application of mathematical modelling and the use of life cycle thinking – also in the field of recovered wood (RW). To this end, the reverse logistics process model CATWOOD (CAscade Treatment of WOOD) with mechanistic modelling for detailed planning of the RW reverse flow with regular collection, innovative (cascade) sorting based on RW quality and environmentally sound recovery has been designed. As a decision support, the quantitative methods of life-cycle assessment (LCA) and societal life-cycle costing (SLCC) have been incorporated into the CATWOOD, which can choose among a few alternative scenarios. A case study has been performed in the Posavje region in Slovenia, which has discovered that reverse logistics scenarios for reuse are environmentally friendlier than those for recycling or energy recovery, but also more costly, mainly because of extensive manual labour needed and less heavy technology involved in sorting and recovery processes. Sensitivity analysis has exposed that modifying the values of the input parameters may change the final LCA and SLCC results in scenarios observed.

“…Many criteria must be considered, and compromise must be made to find a sustainable and viable project. According to [12], many criteria must be considered for a project to be viable and sustainable. The criteria are project cost effectiveness, economic viability and environmental impact, safety improvement, optimized mobility, and accessing and preserving of the existing structure.…”

-The construction sector is one of the indicators of national economic growth and has contributed 4% yearly in average to Malaysia GDP and 6% to the national economy between 1995 -2015. The excellent of construction growth is mainly from projects implemented under "Public-Private Partnership" (PPP) and privatization. Under 10 th Malaysian Plan, 52 projects valuing about RM62.7 billion will be implemented under PFI for infrastructure works. This study aims to evaluate the project viability and the correlation between the costs and revenue collected for entirely concession period. A systematic framework for project viability of highway privatization projects has been developed based on research findings. The methodology adapted in this research is by using descriptive literature technique analysis. The research finding shows that most preferred technique used by respondents are Internal Rate of Return (IRR) and Net Present Value (NPV). In sustaining the highway projects, the costs incurred during concession period should be managed efficiently. Four (4) variables are found for evaluating project's viability and identifying which variables correlate and significantly contributes to the project viability namely operation cost, maintenance cost, actual toll traffic, and revenue. Actual traffic volume significantly correlates with the revenue meanwhile the operation cost is less correlated to the revenue. This research highlighted the viability of the privatized highway projects for entirely concession period and based on the findings, it is suggested a comprehensive framework for future project evaluation comprising of 8 components of commercial and technical evaluation for privatization highways in Malaysia need to be introduced and recommended to be implemented in the industry.
