Currently the toy manufacture is beginning to be interested in greenhouse gas or carbon dioxide equivalent release reduction. Because this is one to way to encourage production cost environment trouble and organization image valve efficiently. The receivable standard for evaluation is carbon footprint for Organization CFO. So this research has objective to study opportunity for initiate CFO in Toy Manufacturing plant case study this CFO is able to evaluate energy consumption and GHG release systematically. This can be used to prepare plan of energy consumption reduction management and reduce GHG release of efficiently. This research was study energy consumption and GHG release by using database of 2010 we found that plant case study was released carbon dioxide 8500 tons CO2 carbon dioxide equivalent by calculated into Scope 1 = 1249 tons CO2 Scope 2 = 6948 tons CO2 equivalent and Scope 3 = 304 tons CO2 equivalent. So the result from this research is being uses important information for planning energy consumption reduction and GHG release of sustainable case study.

Reused cooking oil is the oil which is used more than one time and contains less than 25% (by weight) of polar compounds. Degenerative reused cooking oil is the oil which is used more than two times and contains more than 25% (by weight) of polar compounds. Major raw material of fried foods is oil. Therefore usefulness of consumed fried foods depends on the quality of cooking oil. When the oil is heated up while cooking chemical change occurs due to the reactions of hydrolysis oxidation and polymerization. These reactions cause degeneration of the oil i.e. black color rancid smell lower smoke point bubbled increased viscosity and generation of toxic substances called polar compounds. This substance can cause high blood pressure heart disease and coronary artery disease. Furthermore the reused cooking oil also contains polycyclic aromatic hydrocarbons (PAHs) - toxic mutagens which can cause cancer.

This research presents a study of the compressive strength porosity chloride penetration resistance to carbonation and corrosion of self-compacting concrete containing fly ash ground rice husk-bark ash and ground bottom ash. Portland cement (CT) is partially replaced with pozzolans 0-40% by weight of the cementitious materials. Fly ash ground rice husk-bark ash and ground bottom ash have a high potential to be used as a good cementitious material. The results show that the compressive strength and low porosity of self-compacting concrete improves substantially with partial replacement of Portland cement with fly ash. Self-compacting concrete mix cement containing 20-40% of pozzolans can be used to make cementitious materials. The use of fly ash ground rice husk-bark ash and ground bottom ash produces concrete mix with good strength and resistance to chloride and corrosion.

Polycyclic aromatic hydrocarbons are a group of important organic pollutants and should be concerned. General sources of PAHs are contamination of petroleum hydrocarbons and incomplete combusion of organic compounds. The recalcitrance of these compounds depends on the arrangment of benzene rings and their molecular weight. Besides they are carcinogenic and mutagenic to animals PAHs show several toxicity to plant such as decreasing shoot and root growth and photosynthetic rate. PAHs are toxic to plant at molecular level such as increasing oxidation pressure and decreasing gene expression of cell wall-loosening protein expansion. Photooxidized PAHs showed higher toxicity to plant than parent compounds. Plant species and some environmental factors such as soil pH affect to PAHs phytotoxicity. Phytotoxiciy of Polycyclic aromatic hydrocarbons to crop plant growing in Polycyclic aromatic hydrocarboncontaminated soil is an important environmental concern

Here we present an experimental study of the single-effect adsorption cooling system using activated carbon-methanol working pair. The test unit was comprised of an adsorber a condenser and evaporator in vertical alignment. Heating and cooling of adsorber was mainly done by hot and cold water circulating through the water jacket. The evaporator and condenser was heated or cooled by flows of water through the internal coil. The adsorber was analyzed for its cooling rate when cooling was done by two approaches either cooling water and/or three thermosyphon heat pipes which both methods gave shortest cooling time. The investigated heat source and sink temperatures are; hot water temperature supplied to adsorber (70 80 90 oC) and cooling water temperature supplied to condenser (5 10 15 oC). An ultrasonic wave generator was attached to the bottom end of the evaporator to generate wave frequency varied by 8 10 and 14 kHz during evaporation phase. The ultrasonic wave can obviously reduce the evaporation time of methanol as well as to improve the system performance in terms of COP SCP and VCP. The system performance was considerably comparable to those from literatures. The highest COP and SCP obtained from this system was 0.718 and 248.90 W/kg respectively.
