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.

Supporting the Revolution: America, Democracy, and the End of the Cold War in Poland, 1981-1989. ACES Working Paper (Report) No. 8, 2007

Early on the morning of December 13, 1981, General Wojciech Jaruzelski, the leader of the communist Polish United Workers' Party (PZPR), declared martial law, ending the so-called "Polish Crisis," which began with the creation of the Independent Free Trade Union "Solidamosc" in August 1980. Over the next eight years, the Communist government and the opposition struggled over power, culminating in 1989 with the creation of a Solidamosc-led government which ended fifty years of Communist rule in Poland and led the way to further democratic revolutions throughout Eastern Europe. The purpose of this dissertation is to utilize newly available and underutilized archival sources as well as oral history interviews, from both international and American perspectives, to fully chronicle American policy toward Poland from the declaration of martial law until the creation of the Solidarnosc government. Rather than explaining Polish-American relations in bilateral terms, the dissertation illuminates the complex web of influences that determined American policy in Washington and affected its implementation within Poland. This includes descriptions of internal tensions within the Reagan administration, differences between American decisions in Washington and implementation in Warsaw, lobbying from Polish-American groups, clashes between Capitol Hill and the White House, coordination with American labor organizations to support Solidarnosc, disagreements with West European allies in NATO and international financial organizations, cooperation with the Vatican and the Polish Catholic Church, synchronization with American humanitarian organizations working in Poland, limitations caused by the realities of Soviet power in Eastern Europe, and complications caused by domestic Polish concerns. By taking a broad view of American policy and highlighting internal Polish decisions, with both the Communist government and the democratic opposition, the dissertation provides concrete examples of America's role in Poland's transformation, arguing, however, that this role was very limited. These conclusions are relevant to arguments about the end of the Cold War, the nature of American power, as well as current discussions about possibilities to promote democracy within hostile regimes.
