Building Demolition

In recent year, Korea relies on imports for most of the iron ore, the main raw material of rebar, resulting in CO2 pollution with lots of energy consumption. Hereupon, this study carried out the research on the energy consumption and CO2 emissions of the recycled rebar using the wasted steel from building demolition. For that, this study worked out the energy consumption and CO2 emissions in the process of generation, transportation and production of wasted steel and, on the basis of which, it conducted the comparative study with virgin materials. The major research results are as follows: First, the energy consumption and CO2 emissions of the recycled rebar were found to be highest in the process of its production at 89.2% and 85%, respectively. In addition, in the comparison between recycled rebar and virgin material, the former was found to be most advantageous in energy consumption. On the contrary, as for CO2 emissions, the recycled rebar showed a 88.3% reduction possibility of greenhouse gas (GHG) emissions comparing to statistics of input-output analysis based on competition inducement coefficient, but it was found to be more disadvantageous from the perspective of GHG reduction than the statistics of input-output analysis based on non-competition inducement coefficient.

Production Techniques

Structural changes in economy become the important goal of economic development in the developing countries. During the ongoing globalization process, the successful execution of special analysis and approaches caused the growing interest in macroeconomic planning and development policies. In this context, input-output analysis is emerging as an alternative research method among the other economic planning methods. The purpose of the present paper is to describe the structural changes in production, compare the structural parameteres of production for the years 2005-2009, investigate the sources of differences and give recommendations that will bring solutions to the problems. Research is based on input-output analysis and used input-output tables prepared for the years 2005 and 2009 by The National Statistical Committee Kyrgyz Republic. Industrial structure dependency, production techniques, efficiency of input usage, were calculated in this paper. The results are as follows: there were found some sub-sectors in agriculture, manufacturing and service sector, on which economy depends on; equal efficiency of production techniques and input usage. It is notable that for achieving economic growth, economy needed investments to stimulate the production capacity, which strengthening inter-sectoral relationship and stable macro-economic planning.
