Analysis of CO2 Emission in the Waste Disposal Process Based on Computation of Construction Waste

The purpose of this study is to analyze CO2 emission based on computation of construction waste which occurs during new constructions. To accomplish the purpose, Basic unit data of existing construction wastes was analyzed and basic unit of construction wastes generated during new constructions was proposed. In addition, basic unit of CO2 in the disposal process of construction waste established as the national LCI DB of Korea was applied to analyze CO2 emission during the disposal process of waste (landfill, incineration, recycling) generated during new constructions. As a result, flammable materials showed relatively high emission of 17.75kg-CO2/kg and 2.40kg-CO2/kg for the landfill process and recycling process, and inflammable materials had high emission of 0.74kg-CO2/kg for the incineration process. As a result of analysis for each waste, emission was found to be in decreasing order of landfill and recycling processes for concrete, recycling, landfill and incineration processes for metals, incineration, recycling and landfill processes for wood and flammable materials, and landfill, recycling and incineration processes for inflammable materials.

Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.

As a result of the spread of sewerage systems, the management of growing quantities of sewage sludge is becoming an urgent need. As the method of sludge management, thermal processes have mostly been applied to the treatment and disposal of sewage sludge in Japan, because of the difficulty of finding final disposal sites. This paper describes the progress of thermal processing technologies, especially focusing on drying-incineration process systems and melting-slag recycling process systems.

In their activities, humans produce a large amount of wastes. A sharp increase in consumption resulted in a large volume of solid domestic wastes, which must be combated. All this poses a certain life threat to mankind. However, there is no totally waste-free production. That is why the most effective way of waste disposal should be chosen. That is why it is necessary to choose the most effective way of waste utilization with minimization of environmental and economic risks.
