Abstract

Purpose – This study aims to obtain the best lipid content in locally isolated microalga that grows in palm oil mill effluent (POME).

Design/Methodology/Approach – Microalgae were cultured in POME with 25% dilution (LP25), 50% (LP50), and no dilution (LP) in 1,500 ml glass vessel at room temperature using a lighting intensity of 13,000 lux and continuous aeration for 24 hours and 12 hours, respectively. The biomass (in dry weight) of microalgae was analyzed daily by means of spectrophotometry using 624 nm wavelength to determine their growth.

Findings – The results showed that the acclimatized growth of microalgae in POME media adapted faster to the POME concentration. Acclimatized biomass content tends to increase to 1.014 g/L, while the content of non-acclimatized biomass reached only 0.752 g/L. Lipid content resulting from the direct extraction process using the modified Bligh and Dyer method provided the best yield of 47% in the microalgae grown in the LP50 POME medium.

Research Limitations/Implications – Lipid was produced from locally isolated microalgae cultured in POME medium with 25% dilution (LP25), 50% (LP50), and no dilution (LP).

Practical Implications – The lipid produced had the potential for biodiesel energy.

Originality/Value – In this study, microalga was used not only to treat POME liquid wastes but also to produce lipids as biodiesel energy potentials.

Abstract

Purpose – This chapter compares bioenergy policy developments in Germany and Denmark to better understand the responses of EU country policy regimes to global shocks; to examine potentially emerging new trends of productivist policy models; and to explore potential land use conflicts in the context of a multifunctional EU agricultural policy.

Design/methodology/approach – The chapter reviews the bioenergy policy development pathways taken by Germany and Denmark, highlighting key consequences for agricultural land use and rural development. Findings from both case studies are then compared in summary tables, followed by a discussion of the possible emergence of productivist policy approaches in the bioenergy sector in these countries.

Findings – The bioenergy policies pursued by both countries differ in key respects and yet have had the same result-an increase in the productivist orientation of agriculture, legitimised by the environmental concerns of bioenergy policy. The Danish and German case studies also demonstrate that the particular pathways taken to establish bioenergy policies in each country have been strongly influenced by local political, farming and technological dynamics.

Originality/value – This chapter presents a telling case of what Burton and Wilson (this volume) call “repositioned productivism”, where productivist approaches benefit from environmental or multifunctional policy rationale to continue at the farm level.

Abstract

Over the past decade, biofuels production in the European Union and the United States has boomed – much of this due to government mandates and subsidies. The United States has now surpassed Brazil as the world's leading producer of ethanol. The economic and environmental impact of these biofuel programs has become an important question of public policy. Due to the complex intersectoral linkages between biofuels and crops, livestock as well as energy activities, CGE modeling has become an important tool for their analysis. This chapter reviews recent developments in this area of economic analysis and suggests directions for future research.

Abstract

Ocean transportation is not only the cheapest and the best mode of bulk transport but also the most polluting form of transportation. The International Maritime Organization (IMO) has set strict targets to cut down carbon dioxide (CO2) emissions, following which several initiatives have been taken by the shipping industry to embrace new technologies that can make the industry greener. Significant investments have been made into research and development (R&D) to develop alternative marine fuels. This chapter explores the feasibility of setting up a Biomass Recycling Facility (BRF) in the Tirupur–Tuticorin region in Tamil Nadu. The region was chosen because Tirupur being a textile valley generates tonnes of textile wastes every year. It can become good feedstock for biofuel generation, and it is also near Tuticorin Port, which is one of the major ports in Tamil Nadu. On an average, every year 1,000 vessels of medium and large size call at this port. There is a high probability that a BRF established in the vicinity can generate and supply bioethanol for the ships calling at Tuticorin Port. It is apparent from the findings of the study that the feedstock generated by textile industry alone may not be sufficient to meet the huge volumes of biofuel requirements of vessels, more over considerable investments into infrastructure and technology are required. But the study points out that still it could become a viable option because of the government support and favourable Foreign Direct Investment (FDI) policies. The growing demand for biofuel and the increasing price in the world market can become an added advantage.

Abstract

Purpose

Long haul freight transport imposes huge negative environmental externalities on society. Although these can never be entirely eliminated, they can be reduced. The purpose of this chapter is to analyse some of the many mitigating measures, or interventions, that can be used.

Methodology/approach

The approach used in this chapter is to review the literature and provide an overview of the main theoretical and practical mitigation measures available to transport operators.

Research limitations

There are literally thousands of possible mitigation measures and combinations that can be used by operators to reduce their environmental footprint. Each of these measures warrants a separate chapter. This chapter can only present an overview of the principle available measures. Although some mainland European examples are used, it is acknowledged that the examples used are somewhat skewed towards the United Kingdom.

Originality/value of the chapter

The value of the chapter is in bringing together some of the many measures and approaches that can be used to reduce the environmental externalities of long haul freight transport. Much of the information on such interventions is based on industrial and EU project sources rather than purely academic research and so is less likely to be found in academic journals.
