The study on output allocative efficiency considering the emission trading is meaningful to allocate emission quota in order to promote production efficiency of industry. This chapter studies the output allocation problem with constraints to profit and pollution goals, and proposes three types of output allocative efficiency measures, including the comprehensive output allocative efficiency, the profit-oriented output allocative efficiency based on pollution constraint, and the pollution-oriented output allocative efficiency based on profit constraint, which aim to maximize the total profit and (or) minimize the total pollution. The proposed measures are used to evaluate the output allocative efficiencies of 32 paper mills along the Huai River in China, and different parameters are tested with sensitivity analysis to examine the changes of optimal output combination. This chapter helps the enterprise to optimize the decision of production and helps the government to formulate a reasonable plan of pollution control and treatment.

Purpose – The objective of this chapter is to draw the attention of policy makers in the fields of urban planning and transport in China to the importance of developing more balanced multi-modal transport systems and the corresponding land-use patterns to support transport systems, particularly walking and cycling in order to address the issues arising from the dense, highly mixed land-use pattern in many Chinese cities. This will help to reverse current planning practices which give car-oriented development top priority and less consideration of walking and cycling.

Methodology – Statistical methods have been applied to analyse modal split in some cities in Japan, Beijing and Shanghai using travel surveys, plus analysis of the experience of policies in various cities around the world, especially in terms of the relationship between the modal shares for public transport and car. Door-to-door travel times have been analysed for Shanghai to understand the potential of cycle or e-bicycle in a dense urban environment.

Findings – The change in travel modal split in Beijing in recent years suggests that simply encouraging public transport cannot control use of car. The data from Japan also shows that normal bus services cannot compete with the car, but it is clear that people will travel less by car if there is a high non-motorized share in the city. Because of the low density of the metro network, the door-to-door travel speed by metro is not as fast as is often imagined, due to the long off-metro time. The people who use metro are often not the people who live very close to metro stations, but some distance away, so improving the connection to the station by cycle or e-bicycle could greatly reduce the total travel time by metro.

Research limitations and implications – More analyses should be conducted in medium-size and small-size cities in China, where the local capacity is low and there is great potential to travel by walking and cycling, but only after clear guidance and policy instruments have been provided by higher authorities.

Practical and social implications – There is still a relatively high share of non-motorized travel in China. Many cities still have extensive cycle infrastructure established under the State Code of Urban Road Transport Planning issued in 1995. Encouraging non-motorized transport systems is not only possible, but also good for the environment, and contributes to travel efficiency and social inclusion.

Originality – This chapter is the summary of several original research studies using primary survey data, encouraging public transport in China. This is the first research to show the great potential of non-motorized mode for controlling car use and improving urban mobility in China. It is also the first chapter to point out the integration of multi-modal transport systems with the corresponding built environment in China.

Globalization has increased the consumer's demand for safe and quality foods. To make food available to consumers from farm to fork, packaging plays a crucial role. The objective of packaging is to shield the foodstuff from degrading and to serve as the medium of communication between the processing industry and the consumers. Conventionally, several materials are used in the packaging such as laminates, plastics, glass, metal, etc., but with the advent of technology, newer and novel smart packaging technologies have entered this field. Smart packaging in the form of active and intelligent packaging not only acts as a barrier to external influences but also prevents internal deterioration. Oxygen scavengers, moisture controllers, antioxidants, CO₂ absorber/emitter, antimicrobial agents, etc., are some of the vital active packaging systems. On the other hand, an intelligent packaging system contains internal or external indicators and sensors that monitor the condition of packed food and gives information about its quality during storage and transportation. It seems that these interventions in packaging have very positive effects on the whole industry, but it is observed that this advancement in the packaging has also raised questions about its disposal. To overcome this issue, industries have started using smart packaging design along with the sustainable packaging trend. Communication with the recycling bodies at the time of development will ensure the smart packaging fit to be recycled. Considering such standards for smart packaging will not only create a healthy bond between industries and consumers but will also help in sustainable development. This chapter mainly focuses on the advancement of the packaging system associated with the agri-food sector. It also discusses how the implementation of these technological advancements will help the industries toward sustainable development.

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.

Transnational corporation (TNC)-led oil investments have been widely encouraged as a mechanism for the development of the Global South. Even though the sector is characterized by major accidents, oil-based developmentalist narratives claim that such accidents are merely isolated incidents that can be administratively addressed, redressed behaviorally through education of certain individuals, or corrected through individually targeted post-event legislation. Adapting Harvey Molotch’s (1970) political economy methodology of “accident research”, this paper argues that such “accidents” are, in fact, routine in the entire value chain of the oil system dominated by, among others, military-backed TNCs which increasingly collaborate with national and local oil companies similarly wedded to the ideology of growth. Based on this analysis, existing policy focus on improving technology, instituting and enforcing more environmental regulations, and the pursuit of economic nationalism in the form of withdrawing from globalization are ineffective. In such a red-hot system, built on rapidly spinning wheels of accumulation, the pursuit of slow growth characterized by breaking the chains of monopoly and oligopoly, putting commonly generated rent to common uses, and freeing labor from regulations that rob it of its produce has more potency to address the enigma of petroleum accidents in the global south.

Bioenergy remains the largest branch of renewable energy, and microalgae are a promising object of research among other types of biomasses whose scale for energy purposes is increasing. On the other hand, the growth of global energy production and urbanization, which results in high rates of municipal waste and wastewater generation, requires the development of integrated technologies that allow waste to be disposed of as fully as possible. Sustainable investments in the production of energy by various technologies are one of the methods to solve this complex problem. In this chapter, we study the methods of microalgae utilization of nutrients from wastewater and by-product liquid waste of sustainable investments from microalgae by hydrothermal liquefaction (HTL) technology. Wastewater has a complex composition, and the treatment of nitrogen and phosphorus and other biogenic elements, as well as heavy metals, using biological objects is optimal and cost-effective. Also the water phase after HTL is a by-product that has limited energy value. Biofuel investments have higher growth rates and at the same time do not compete with the investments in fossil fuels. Biofuel investments' cost of seaweed fuel can be reduced through high-value-added related products, such as food and feed additives, and pharmaceutical and cosmetic products.
