Se determinó la efectividad de hongos filamentosos degradadores polietileno baja densidad (LDPE), aislados residuos plásticos provenientes del botadero basura distrito Sicuani, Provincia Canchis, Región Cusco; durante el año 2018. Las muestras fueron seleccionadas y puestas a pruebas degradación por técnica Kavelman Kendrich, enmedio mineral (MSM) suelo. especies micromycetos se identificaron K...

This study reports an application of instrumental color measurement for quantifying and comparing the optical properties of high density polyethylene HDPE and low density polyethylene LDPE blend films and the effect of blending ratio and miscibility on these properties. The technique of spectrophotometry in transmission and reflectance modes can be used as a versatile tool to evaluate the color...

Antibacterial properties of TiO2, ZnO as well as mixed TiO2-ZnO nanoparticles coated low density polyethylene films on Staphylococcus aureus PTCC1112 were investigated. Bactericidal efficiency of 0.5, 1 and 2 Wt% for TiO2 and ZnO nanoparticles and also 1 Wt% mixed TiO2-ZnO nanoparticles with TiO2:ZnO ratios of 25:75, 50:50 and 75:25 were tested under UV and fluorescent lights exposure at two di...

Hazardous compounds emitted during the plastic melting process were analyzed to indicate potential air pollution issues associated with recycle plants for waste plastics. These hazardous compounds might be not only from polymer degradation but also from additives and print ink. To confirm what are emitted from them, melting experiments were conducted (150, 200 and 250°C, in air or N2) and volat...

The maintenance of the quality and storage life of perishable fruits and vegetables is a major challenge for the food industry. In this study, the effects of different temperatures, packaging materials and storage time on the stability of capsaicinoids and antioxidants, such as total carotenoids, ascorbic acid and total phenolic compounds, were studied in three commercially cultivated hot peppe...

Sampah plastik merupakan jenis sampah yang sulit terurai, oleh karena itu perlu adanya pegolahan kembali seperti dijadikan bahan bakar mempunyai nilai jual tinggi khususnya kalor. Low Density Poly Ethylene (LDPE) memiliki kalor sangat tinggi, namun akan cepat habis jika dibakar kadar volatile matter-nya mencapai 98,53%. Untuk itu, dikombinasikan biomassa dengan matter rendah tandan kosong kelap...

Low density polyethylene (LDPE) is used for packaging and other industrial application a significant source of environmental pollution. The present study was aimed at testing the ability bacterial strains identified as Bacillus cereus Pseudomonas aeruginosa to degrade LDPE. These were isolated from soil samples collected dump site. All isolates screened their synthetic produced weight loss perc...

Waste Low density polyethylenes (LDPE) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. Calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. The effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. The effect of catalyst o...
