In everyday life the use of plastic materials is very dominant. The this material from year to has greatly increased, which resulted in an increase waste. Various parties have conducted research reduce waste into something that can added value, including converting alternative energy sources form fuel. Handling be done by recycling it heating a reactor so becomes liquid oil, then oil purified u...

Given that plastic is typically only used once, increasing levels of waste in TPA make it difficult for Indonesia and even the rest world to solve problem trash (final disposal sites). Performing a field investigation literature review comes first. Making blade model distinct from previous one involves using findings survey study. According examination most recent blades, which have angles 30° ...

in the present research, effects of modified atmosphere packaging (map) includingthree gas combinations and two packaging films (low density polyethylene (ldpe) andpolypropylene (pp)) on postharvest quality and storage-life of 'elberta' peach wereevaluated. the study was conducted as a factorial experiment based on crd(completely randomized design) with three replicates for 9 weeks. f...

The low-density polyethylene/aluminum (LDPE/Al) joint in Tetra Pak provides stability and strength to food packaging, ensures protection against outside moisture, maintains the nutritional values flavors of without need for additives products. However, a poor adhesion LDPE Al, due its non-polar surface, is limiting factor extra polymeric interlayers or surface treatment required. Plasma-assiste...

Nowadays, plastic materials are extensively used in the agri-food sector for multiple purposes. The end-of-life management of these plastics is an environmental challenge because frequent incomplete recoveries after crop seasons lead to accumulation debris agricultural waste, which now recognized as emerging issue global concern. However, effects waste undergoing biotreatment have been poorly s...

This study aimed to establish primary reactions and identify gaseous products during fast pyrolysis of low-density polyethylene (LDPE), polypropylene (PP) polystyrene (PS). Fast was performed by using Py-GC/MS/FID at 574 ± 22 °C for 5 s. Gaseous fractions formed LDPE, PP PS were 14 1 wt%, 31 3 wt% 103 12 respectively. The main compounds from LDPE butane, 1-pentane 1-hexene. gave propene, pentan...
