The energy efficiency, mechanical durability, and environmental compatibility of all moving machine components rely heavily on advanced lubricants for smooth safe operation. Herein an alternative family high-quality liquid (HQL) was derived by the catalytic conversion pre- post-consumer polyolefin waste. plastic-derived performed comparably to synthetic base oils such as polyalphaolefins (PAOs)...

Abstract Citrus aurantium amara (sour orange) belongs to one of the largest genera Rutaceae family. The species this genus are consumed worldwide as fresh or in form beverages. They include well-known crops lemons, oranges, mandarins, grapefruits, and limes. industrial processing these fruits produces high amounts waste (around 50%) which is a valuable source essential oils. Since they produced...

Nigeria faces the challenge of organic waste, which is imported into the country. These wastes cause serious menace to human health, and environment, with reverberation, further afield. Baseline inventory of PCB contaminated oils and equipment had been conducted in Nigeria, albeit not exhaustive. However, the report from this study point to streams of contaminated oils and equipment, with possi...

The study aimed to analyze the possibility of waste frying oil utilization in home-made soap production. Soaps were made from unheated and fried rapeseed, sunflower palm oils that had total polar material (TPM) values up 24%. Physicochemical microbial analyses performed on produced samples check their quality. hardness increased with degradation level rapeseed oils, opposite findings obtained f...

Initial results are presented for the production of hydrogen from waste lubricating oil using a chemical looping reforming (CLR) process. The development of flexible and sustainable sources of hydrogen will be required to facilitate a ‘hydrogen economy’. The novel CLR process presented in this paper has an advantage over hydrogen production from conventional steam reforming because CLR can use ...

Although PHAs are regarded as an effective substitute for conventional plastics for a number of medical and agricultural applications1 and food packaging2, their full-scale manufacturing is hampered by high production costs3. Factors affecting the cost of PHAs include raw materials availability, suitable process design, and downstream processing4,5. Since almost 50 % of the total production cos...
