Assessing construction and demolition waste on masonry works to avoid future generation

The difficulty of dealing with construction and demolition waste (CDW) on construction sites is not new and continues to be a significant environmental problem. Currently the CDW collection system in Spain is done in a decentralized manner by each sub-contracted company, being necessary to implement effective waste management measures ensuring a correct management and minimization. During the last years several measures have been launched in order to improve and encourage the reuse and recycling of CDW. A widespread solution for CDW recovery is using them as a landscaping aggregate or for road bases and sub-bases. However, measures encouraging onsite prevention still need to be enhanced. This paper studies the major work stage generating CDW and analyses the categories of CDW produced during its execution. For this, several real building sites have been analysed in order to quantify the estimation of CDW generated. Results of this study show that a significant contributor to the CDW generation on building construction sites in Spain are the masonry works. Finally, a Best Practices Manual (BPM) is proposed containing several strategies on masonry works aimed not only at CDW prevention, but also at improving their management and minimization. The use of this BPM together with the Study and Plan of CDW management --required by law--, promotes the environmental management of the company, favouring the cohesion of the construction process organization at all stages giving rise to establishing responsibilities in the field of waste and providing a greater control over the process. Keywords: construction and demolition waste, management, masonry works, good practice measures, prevention.

The situation in Syria at the beginning of 2013 could hardly be worse. Dead, wounded, refugees, a humanitarian disaster. President Assad is destroying his country and waging war against his own people. Russia and Iran back the regime. The West wants regime change without intervening militarily. The political opposition is now more united but overwhelmed with the situation at hand. The armed resistance, partially dominated by Jihadists, is difficult to size up.

Syria: An end to the hands-off policy. CEPS Commentary, 31 August 2015

After a year of focusing on the nuclear deal with Iran, international diplomacy is returning to consider resolution of the civil war in Syria, with each side now a little less firm in their positions as the situation on the ground deteriorates further. In this new CEPS Commentary Steven Blockmans sheds light on the highly complex and volatile environment in the Middle East, concluding that failure to seize the new diplomatic momentum to resolve this conflict will likely mean that Syria falls into the hands of IS.
