Abstract

Purpose – This work aims to study the treatment of adsorbant on the increasing liquid hydrocarbon quality produced by pyrolysis low density polyethylene (LDPE) plastic waste at low temperature. The hydrocarbon distribution, physicochemical properties and emission test were also studied due to its application in internal combustion engine. This research uses pure Calcium carbonate (CaCO3) and pure activated carbon as adsorbant, LDPE type clear plastic samples with control variable that is solar gas station.

Design/Methodology/Approach – LDPE plastic waste of 10 kg were vaporized in the thermal cracking batch reactor using LPG 12 kg as fuel at range temperature from 100 to 300°C and condensed into liquid hydrocarbon. Furthermore, this product was treated with the mixed CaCO3 and activated carbon as adsorbants to decrease contaminant material.

Findings – GC-MS identified the presence of carbon chain in the range of C6–C44 with 24.24% of hydrocarbon compounds in the liquid. They are similar to diesel (C6–C14). The 30% of liquid yields were found at operating temperature of 300°C. The calorific value of liquid was 46.021 MJ/Kg. This value was 5.07% higher than diesel as control.

Originality/Value – Hydrocarbon compounds in liquid produced by thermal cracking at a low temperature was similar to liquid from a catalytic process.

Abstract

The increasing accumulation of synthetic plastic waste in oceans and landfills, along with the depletion of non-renewable fossil-based resources, has sparked environmental concerns and prompted the search for environmentally friendly alternatives. Biodegradable plastics derived from lignocellulosic materials are emerging as substitutes for synthetic plastics, offering significant potential to reduce landfill stress and minimise environmental impacts. This study highlights a sustainable and cost-effective solution by utilising agricultural residues and invasive plant materials as carbon substrates for the production of biopolymers, particularly polyhydroxybutyrate (PHB), through microbiological processes. Locally sourced residual materials were preferred to reduce transportation costs and ensure accessibility. The selection of suitable residue streams was based on various criteria, including strength properties, cellulose content, low ash and lignin content, affordability, non-toxicity, biocompatibility, shelf-life, mechanical and physical properties, short maturation period, antibacterial properties and compatibility with global food security. Life cycle assessments confirm that PHB dramatically lowers CO2 emissions compared to traditional plastics, while the growing use of lignocellulosic biomass in biopolymeric applications offers renewable and readily available resources. Governments worldwide are increasingly inclined to develop comprehensive bioeconomy policies and specialised bioplastics initiatives, driven by customer acceptability and the rising demand for environmentally friendly solutions. The implications of climate change, price volatility in fossil materials, and the imperative to reduce dependence on fossil resources further contribute to the desirability of biopolymers. The study involves fermentation, turbidity measurements, extraction and purification of PHB, and the manufacturing and testing of composite biopolymers using various physical, mechanical and chemical tests.

Abstract

Every year, tens of millions of the 1.4 billion cars on the world’s roads are decommissioned. While the ferrous and other metals that constitute about 75% of a vehicle by weight can be readily and profitably recycled, the remaining mix of plastics, glass, composites, complex materials, fragments and contaminants are mainly destined for landfill as automotive shredder residue (ASR). For every car, approximately 100–200 kg of ASR is disposed of in landfill, posing a growing technical and environmental challenge worldwide. The recovery of the ASR for high-end application is the focus of this study, aiming to optimise the use of these valuable resources and minimise the extractive pressure for raw materials, a future green manufacturing, contributing towards a zero waste circular economy. As the dissolution of carbon into iron is a key step in the manufacture of iron-carbon alloys, the feasibility of utilizing the waste polymers within ASR as sources of carbon in different areas of pyrometallurgical processing was investigated. Polypropylene and rubber, in a blend with metallurgical coke, were used as carbonaceous substrates and the slag-foaming phenomenon was investigated via the sessile drop technique in an argon environment at 1,550°C. The results indicated the rubber/coke blend achieved significantly better foaming behaviour, and the PP/coke blend exhibited a moderate improvement in slag foaming, in comparison to 100% metallurgical coke. The overall results indicated the incorporation of ASR had significant improvement in foaminess behaviour, increasing furnace efficiency.

Abstract

Plastic has been a very useful material which is very cheap, easy to carry and is resilient to biodegradation. That is why plastic has been used, sometimes reused, and overused due to the reasons mentioned above. As a result, landfills and oceans are full of plastic. But if we consider all the negative health effects, environmental / ecological effects it has in present times, we can understand that it is environmentally very expensive to use plastic. Bangladesh is a relatively young country with dense population and limited resource. Proper management of plastic remains an issue with the country. Considering these, this chapter focuses on how plastic is used, how it is treated as waste and what can be possible solutions in reducing the amount of plastic in Bangladesh.

Abstract

Plastic waste is one of the long-standing global issues in the recent era. Unfortunately, India is one of the countries which has been affected by the mismanagement of the use of plastics. India has recorded a substantial growth in the production of plastic and is considered a country of increased consumption of plastic. Due to the absence of an appropriate waste collection and segregation process, it has created the major issue of waste management and discarded used plastic items used for packaging application. There are various plastic waste management laws and programmes that have a cascading effect on almost every sector of business. In 2016, two years after the new union government took power in New Delhi, The Ministry of Environment, Forest and Climate Change (MoEFCC) has made some improvements in rules for the collection, segregation, processing, treatment and disposal of the waste. In the pandemic era, effective plastic waste management became more important than ever. The COVID-19 pandemic has created an increased demand for single-use plastic because of pressure on the already out-of-control global plastic waste problem. It is recorded to be large, and the magnitude of this pandemic related to mismanaged plastic waste is unknown. However, understanding the changing landscape and alarming need for effective plastic waste management, the government of India has proposed certain changes to prohibit imports, handling, manufacturing and use of single-use plastics in the country. This is in line with the government's intent to phase out single-use plastic by 2022. Considering this, this chapter highlights the changes in the rules and regulations in India related to plastic waste management and its effects on various sectors of business.

Abstract

This chapter examines the oil and gas industry and the efficacy of vertical integration strategies. Using multiple theoretical lenses ranging from the resource-based view, transactions costs, and parenting perspective, the chapter considers different arguments associated with vertical integration. The 2011 breakup of ConocoPhillips and its global value chain helps address the question of which strategy is best – integrated or nonintegrated. We provide several conclusions about the structure of integration and value chains within the oil and gas industry. First, vertical integration based on the physical transfer of products between value chain activities will generate little firm advantage in the form of classical integration benefits, such as control over input quality or speed to market. Second, competing across the industry value chain as a hedge or strategy against industry cyclicality is not theoretically defensible. Third, pure play industry specialists can create value through management focus, agility, and, transparency for investors. Fourth, firms that compete across a wide range of industry value chain activities can create value-adding corporate strategies if they are able to leverage knowledge and assets across different industry sectors.

Abstract

In the 1930s, chlorofluorocarbons (CFCs) were developed as safe, non-reactive alternatives to toxic and explosive refrigerants and propellants such as ammonia, chloromethane, and sulfur dioxide. American engineer Thomas Midgley famously demonstrated these properties by inhaling Freon (CFC-12) and blowing out a candle with it. He was presented with many awards for his discoveries, such as the Perkin, Priestley, and William Gibbs medals. In today's jargon, CFCs might have been called an eco-innovation, because they provided solutions to several environmental issues. However, CFCs solved environmental problems by creating others. In 1974, Sherwood Rowland and Mario Molina published their pathbreaking research that demonstrated CFCs were depleting the ozone layer. In 1989, the Montreal Protocol, which regulates a global phaseout of CFCs, entered into force. A few years later, in 1995, Rowland and Molina received the Nobel Price in Chemistry. The new substitutes for CFCs, hydrofluorocarbons (HFCs), have no known effects on the ozone layer but are extremely potent greenhouse gases (GHGs) and thus subject to the Kyoto Protocol.

Abstract

Elmar Mock's extraordinary story began in a small village in Switzerland. Born in 1954, he was the son of an Austrian immigrant and a Swiss mother. School was difficult, as he struggled with dyslexia. Nevertheless, he graduated from engineering school, obtained a job with a Swiss manufacturer, ETA. By the age of 26, he had co-invented the Swatch. Following the accidental death of his brother, Stéphane, in 1985, he decided to leave his job and launch his own creativity and innovation consulting company, Creaholic, in 1986.

In 2014, Elmar retired from Creaholic and created with his second wife Hélène Mock née Kett, a second company: ‘Mock-Kett’. He has created more than 80 families of patents in various industries and has been involved in more than 600 projects. He is also a member of the advisory boards of some of the spin-offs incubated by Creaholic. He remains active as a speaker and international consultant with ‘Mock-Kett’, which promotes the motivational side of invention. He has received numerous awards and his book ‘The Innovation Factory’ has been published in three languages.

The case depicts a one-of-a-kind creative mindset and offers in-depth reflections on the concepts of creativity, innovation and intrapreneurship and their applications in organizations. 1
