A novel strategy of waste recycling of polypropylene plastics (PP) bags for generation of commercially viable byproducts using nanoforms of nickel as catalyst is presented in this work. After pyrolysis of waste PP bags (>20 μm) under continuous argon flow, 90% conversion efficiency to high petroleum oil was observed at 550°C. To assess the physicochemical attributes of formed oil, flash point, pour point, viscosity, specific gravity, heating value, and density were also measured and found to be very close to ideal values of commercial fuel oil. Moreover, GC-MS was used to resolve the range of trace mass hydrocarbon present in the liquefied hydrocarbon. Our robust recycling system can be exploited as economical technique to solve the nuisance of waste plastic hazardous to ecosystem.

Chlorella samples were pyrolysed in a fixed bed reactor with γ-Al2O3 or ZSM-5 molecular sieve catalyst at 600°C. Liquid oil samples was collected from pyrolysis experiments in a condenser and characterized for water content, kinematic viscosity and heating value. In the presence of catalysts , gas yield decreased and liquid yield increased when compared with non-catalytic pyrolysis at the same temperatures. Moreover, pyrolysis oil from catalytic with γ-Al2O3 runs carries lower water content and lower viscosity and higher heating value. Comparison of two catalytic products, the results were showed that γ-Al2O3 has a higher activity than that of ZSM-5 molecular sieve. The acidity distribution in these samples has been measured by t.p.d, of ammonia, the γ-Al2O3 shows a lower acidity. The γ-Al2O3 catalyst shows promise for production of high-quality bio-oil from algae via the catalytic pyrolysis.

The city of Surabaya is the second largest city after Jakarta and of course is inhabited by millions of peoplewho produce trash every day, especially plastic waste which is mostly produced from used food containers,plastic cups, straws and plastic bags. Various methods are used by the government to overcome this problemso that the city of Surabaya can become a cleaner and more beautiful city. One community in Surabaya calledthe Waste Recycling Project is a caring community, focusing on the waste recycling activities in Surabaya.The Waste Recycling Project community is able to change the form (transformation) of waste into functionalgoods. This encourages this community to have a place where it can be developed into a community tourismdestination with a Human Centered Design approach where people and tourists can come to visit the WasteRecycling Project to tour and learn together about plastic waste management. This interior design is focusedon designing a community place that can accommodate gathering activities for service learning, space forplastic waste recycle workshop activities, and as a forum for aspirations of creative ideas as well as a gatheringplace for people who have interests and concerns for the surrounding environment.

Plastics have become an essential part of modern life today. The global production of plastics has gone up to 299 million tonnes in 2013, which has increased enormously in the present years. The utilization of plastics and its final disposal pose tremendous negative significant impacts on the environment. The present study aimed to investigate the thermal and catalytic pyrolysis for the production of fuel oil from the polyethene plastic wastes. The samples collection for both plastic wastes and clay catalyst, sample preparation and pyrolysis experiment for oil production was done in Laroo Division, Gulu Municipality, Northern Uganda Region, Uganda. Catalysts used in the experiment were acid-activated clay mineral and aluminium chlorides on activated carbon. The clay mineral was activated by refluxing it with 6M Sulphuric acid for 3 hours. The experiment was conducted in three different phases: The first phase of the experiment was done without a catalyst (purely thermal pyrolysis). The second phase involves the use of acid-activated clay mineral. The third phase was done using aluminium chlorides on activated carbon. Both phases were done at different heating rates. In purely thermal pyrolysis, 88 mL of oil was obtained at a maximum temperature of 39ºC and heating rates of 12.55ºC /minute and reaction time of 4 hours. Acid activated clay mineral yielded 100 mL of oil with the heating rates of 12.55ºC/minute and reaction time of 3 hours 30 minutes. While aluminium chlorides on activated carbon produced 105 mL of oil at a maximum temperature of 400ºC and heating rates of 15.5ºC /minute and reaction time of 3 hours 10 minutes. From the experimental results, catalytic pyrolysis is more efficient than purely thermal pyrolysis and homogenous catalysis (aluminium chlorides) shows a better result than solid acid catalyst (activated clay minerals) hence saving the energy needed for pyrolysis and making the process more economically feasible.

To Receive

About 80% of the total pollution from ships is caused by operational oil discharges into the sea, often made deliberately and in violation of international rules; the main reasons can be due to cost savings or lack of adequate facilities in ports to receive waste oils. Therefore, reducing waste oil discharges is crucial for a proper protection of the marine environment. In this regard, the paper presents the preliminary feasibility of a particular waste recycling technology, aimed at obtaining marine fuel oil from sludge, through a pyrolysis process to be carried out in a small reactor onboard. The originality of the research consists in the adaptation of pyrolysis to oily waste produced by ships, since this technology is traditionally applied to solid waste and biomass. Furthermore, the plant has to be designed for operation on board the ship, therefore under very different constraints compared to traditional land plants. Although the preliminary lab tests and simulation results in the chemical process are promising enough, there are still some technical criticalities due to the energy optimization of the reactor for an efficient use onboard of the whole system. In addition, the possibility of recycling waste, directly onboard ships, is not yet covered by mandatory regulations, which is why shipowners generally still feel unmotivated to invest in such technologies.
