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.

Purpose – The purpose of this research is to study the process conditions that give best yield and expected compositions of liquid smoke products that result during the pyrolisis process relying on predetermined variables.

Design/Methodology/Approach – Pyrolisis process running times are varied, that is, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, and 6 hourly. Condensing temperature maintained remained 25–30 °C. Products identification was applied by using gas chromotography mass spectroscopy.

Findings – Based on the research output, it was concluded that process conditions which give maximum yield were achieved when using double unit condenser (DUC) and time optional four hours, and it provides maximum volume liquid smoke product, and compositions of pyrolisis products. The process also created seven components, namely nepthalene, propanoic acid, 3,7 nanodiena, 2 metilguaiakol, 2-metoksi 4-methyl phenol, 4 ethyl-2 metoksil phenol, oxybanzene. Applying DUC during condensation phase may increase condensing force thereafter obtaining resulted products between 200% and 300% rather than using single unit condenser (SUC).

Research Limitations/Implications – This research was conducted on a fixed batch reactor made of a metal plate with a thickness of 3.0 mm. It carries 200 kg in capacity. In this phase, the moisture of candlenut shells might be kept in 10–12.5% wt. Process temperature applied ranged within 350–500 °C.

Originality/Value – In addition the study increased the theorical of understanding about pyrolisis process and Improving the production of liquid smoke from candlenut shell by pyrolisis process using the method of vapor condensation (Double unit condensor).

The Cyclic Innovation Model is applied to a new process for the production of fine chemicals and pharmaceuticals using a combination of ionic liquids and supercritical carbon dioxide. This multi-value innovation combines economic growth with environmental concerns and social value. The most important obstacles in the implementation of this new technology are the successful life cycle management of current production plants, the linearity of current innovation thinking, and a perceived high risk of adoption.

We assess whether smaller investors are more likely to hold shares of closed-end funds that invest more heavily in illiquid securities. We also examine the relationship between the liquidity of the securities held in the portfolios of closed-end mutual funds (portfolio liquidity) and the liquidity of the closed-end funds’ shares (fund-share liquidity). Using a sample of 1,619 fund-years from 2010 to 2012, we find that smaller investors are more likely than institutional investors to own closed-end funds. We also find that the liquidity of closed-end funds’ portfolios is positively associated with the liquidity of the funds’ shares. Our findings are consistent with the “liquidity benefits” notion that closed-end funds are a means for smaller investors to invest in less liquid securities. In addition, our findings are consistent with the “valuation skepticism” notion which indicates that, due to the difficulty of objectively valuing illiquid securities, different perceptions of the value of illiquid securities held in funds’ portfolios may result in greater fund-share liquidity.

Purpose: In this chapter, the authors posit that, shadowing the etiological crises in criminology, much crime media scholarship remains “lost in the mediascape.” The authors outline why dominant positivist methodologies in crime media scholarship leave us lost and offer tools that researchers may use for better wayfinding in this complex and dynamic environment.

Methodology/approach: Drawing on the concept of liquid criminology, the authors join a growing chorus in the crime media field calling for methodological and theoretical concepts more reflective of the social dimensions of liquid modernity, that is, uncertainty, ambiguity, impermanence, precarity, etc.

Findings: The conditions of liquid modernity inform a mediascape characterized by an abundance of data, misinformation, disinformation, propaganda, and conspiracy theories resulting in collective disorientation and the inability to form coherent narratives about the past, present, or future. As such, these conditions defy positivistic conventions like representative sampling and demand new, imaginative approaches to the study of crime media. To that end, informed by the cultural criminological perspective, the authors offer two methodologies and one theoretical concept.

Research limitations: The authors believe our methodological and theoretical suggestions are best suited for analyzing themes and concepts among discourse around crime incidents that have significant legal and social implications. The authors offer no definitive answers, but hope to begin building a better toolbox for wayfinding in this digital wilderness.

Originality/value: The currently dominant methodology within crime media scholarship is a poor fit with contemporary media culture. Here, the authors begin to remedy that by proposing an orientation that fits better with the fluid, uncertain, and dynamic media environment that permeates our social world.

In their work on ‘online consumer stewards’ in E-sports, the authors point to the competing social and commercial imperatives that govern behaviour and who can be seen as ‘authentic’ in a fast-paced digital environment. Drawing on insights from Bauman’s work on ‘liquidity’ they explore the case of Starcraft II, a global, multi-player online game, and show how the most successful stewards need to be both adaptable and free-floating whilst at the same time anchored in solid community structures. The most successful of these stewards are then able to leverage this (perceived) authenticity to meet both community and commercial objectives.
