Abstract The utilization of gypsum board and fly ash waste as alternative materials in making bricks is one the efforts to reduce amount industrial construction sector, namely waste. use cannot be separated from relatively large potential pollute environment. pozzolanic properties contained combined with are expected improve quality bricks. purpose this study was determine value compressive str...

Abstract The production of concrete will produce a lot carbon dioxide and pollute the environment. Phosphogypsum is solid waste generated during wet phosphoric acid treatment, use phosphogypsum blending instead cement in can effectively reduce emissions. Then, experiments were conducted for six groups with different content as 0%~50% to test strength 3 days, 7 28 days. results show that curing ...

Abstract Metals form an essential part of the Universe at all scales. Without metals we would not exist, and look completely different. are primarily produced via nuclear processes in stars, spread out through winds or explosions, which pollute surrounding space. The wanderings in-and-out astronomical objects crucial determining their own evolution thus that as a whole. Detecting assessing rela...

The application of an environmentally sound industry is one the environmental conservation issues and a global issue in industry. can be implemented Green Manufacturing system. tofu production process uses high volume water, resulting liquid waste, which pollute environment. problem with Sari Kedelai that there has not been performance measurement on environment analysis impact. This study aims...

Urban agricultural activities can have a minimum or substantial contribution to the livelihoods of people. They either conserve pollute environment and degrade land. The information about ensuring productivity with less effect on is dynamic causes dynamisms are not clear. study was conducted examine cause in relation changing institutional frameworks political regimes. used qualitative research...

The process of stockpiling reclamation areas and disposing waste streams can pollute the environment cause attendance dangerous heavy metals. In this research was conducted to determine metals Cd, Fe, Hg, Pb levels in water sediment on Losari beach. method used an atomic absorption spectrophotometer. result showed that Cd Fe for north point were 0.0278 0.0432 mg/L, south 0.0031 0.0674 around pl...

The corrosion phenomenon affects several low carbon steel structures leading to excessive expenditure on coatings and other alternatives. However, the used usually contain compounds that pollute environment. Therefore, environmentally friendly, economical transparent or films have been developed. sol-gel method is a reliable way for development of anticorrosive films, as case alumina silica fil...

The pharmaceutical industry liquid waste is one of the wastes that have potential to produce containing heavy metals. One highest metal contaminants originating from lead (Pb). Pb can cause health problems and pollute environment. way treat by adsorption process using bioadsorbent. eggshell be used as an adsorbent absorb contains calcium carbonate, therefore it adsorbent. This study aims determ...

Aquacultures are of great economic importance worldwide but pollute pristine headwater streams, lakes, and estuaries. However, there are no in-depth studies of the consequences of aquacultures on dissolved organic matter (DOM) composition and structure. We performed a detailed molecular level characterization of aquaculture DOM quality and its bacterial degradation using four salmon aquaculture...

The abundant fruit hulls of tea-oil tree (Camellia oleifera) are still underutilized and wastefully discaded to pollute the environment. In order to solve this problem and better utilize the fruit hulls of C. oleifera, a microwave-assisted extraction system was used to extract their polyphenols using water as the extraction solvent. A central composite design (CCD) was used to monitor the effec...
