亚热带河口陆基养殖塘底泥甲烷产生动力学研究

河口区陆基围垦养殖塘是重要的温室气体排放源,但其底泥甲烷产生动力学特征目前尚未厘清.本研究对我国东南沿海亚热带闽江河口、木兰溪河口和九龙江河口的6个南美白对虾（Penaeus vannamei）养殖塘底泥进行了为期60 d的室内厌氧培养,并对甲烷累积产量曲线利用一阶动力学模型及改进的岡珀茨模型进行拟合和分析.结果表明,所有河口陆基养殖塘底泥产甲烷过程是一个动态变化过程,可分为延滞、产生和稳定3个阶段.延滞期发生在培养初期1~4 d,产生期主要集中在4~25 d,在培养25 d后,所有养殖塘底泥的甲烷累积产量曲线趋于平衡.盐度和孔隙水DOC浓度均能够影响养殖塘底泥甲烷产生动力学拟合参数.随着养殖塘底泥盐度的增加,甲烷最大产生潜力由5961 ng·g^-1减少至559 ng·g^-1,甲烷最大产生速率由674 ng·g^-1·d^-1减少至84 ng·g^-1·d^-1.研究表明,一阶动力学模型更适合低盐养殖塘底泥甲烷产生动力学过程的拟合,而改进的岡珀茨模型更适合高盐养殖塘底泥甲烷产生动力学过程的拟合.选择近海养殖塘进行南美白对虾养殖及在甲烷产生期来临之前清除底泥可极大程度地减少养殖塘底泥温室气体CH₄的产生潜力.     

Innovation cycles,niches and sustainability in the shrimp aquaculture industry in Thailand

In this paper we explain how a shift from culture of the black tiger shrimp (Penaeus monodon) to the Pacific white shrimp (Litopenaeus vannamei) took place during 2002–6 in Thailand. We use system innovation theory to help explain how niche substitution led to a regime change within a Thai aquaculture industry trying to maintain international competitiveness but under pressures from a global landscape in which consumers are increasingly concerned with health and ecological sustainability. Support from a vertically integrated major firm, an extensive foundation of learning networks within the industry, and early profitability made the scaling-up and embedding of the experiment with white shrimp very rapid once the formal ban on import of exotic broodstock was lifted. Disease management with domesticated, specific pathogen-free strains of white shrimp has proven much easier than with black shrimp still dependent on capture of wild broodstock. Moreover relative production costs are lower. The switch in species had significant consequences for the environment and firms. Using life cycle analysis we found that rearing white shrimp requires less resource and produces less waste than black shrimp. The shift in regime, however, also made it more difficult for small farms and hatchery businesses.     

The conceptual model of an eco-industrial park based upon ecological relationships

The necessity to follow the rules of sustainable development in the everyday industrial practice has led to the formulation of the concept of an industrial ecosystem mimicking the natural ecosystem. Following this analogy, the conceptual model of an eco-industrial park, which is an organised form of the industrial ecosystem, was presented in this paper. The model comprises of (1) the structure of the ecosystem, (2) the classification of the enterprises as producers, consumers and decomposers, (3) mass and energy flows and (4) types of interactions. The classification of the enterprises introduced here as well as the analysis of mass and energy flows indicates that the diversity of the enterprises in eco-industrial parks is desired. Furthermore, the minimal condition to create the symbiotic relationships between the enterprises is established, claiming that at least one industrial producer or decomposer must be involved in the eco-industrial park. The application of this model will facilitate the design and development of eco-industrial parks and enable the identification of symbiotic relationships between the entities of such a park and other types of industrial ecosystems. In order to show the applicability of the proposed model and its potential for the practical implementation two case studies are presented.     

Industrial ecosystems as technological niches

In this paper we consider industrial ecology as a novel and distinct state in the evolution of production systems trajectory. More specifically, adopting an evolutionary institutionalist's perspective at the socio-technical system level of analysis, we discuss the transition towards an industrial ecology-inspired industrial production system through the governance approach of strategic niche management (SNM). Towards this end, the paper first develops industrial ecology as a novel state of the industrial production socio-technical system paying particular attention at its technological component, then it discusses in detail the transition of this system through SNM, and examines whether existing implementations of the industrial ecology (industrial ecosystems and eco-industrial parks) are efforts embracing this philosophy and transition procedures. We conclude by stressing the importance of adopting the technology policy and strategic niche management perspectives in eco-industrial projects and we provide insights for accomplishing it in a more effective manner.

Industrial symbiosis and the policy instruments of sustainable consumption and production

Industrial symbioses (ISs) and eco-industrial parks (EIPs) are key concepts of industrial ecology (IE). The aim of ISs and EIPs is to minimise inefficient material and energy use by utilising local by-product and energy flows. Industrial symbioses tend to develop through spontaneous action of economic actors, for gaining of economic benefit, but these systems can be designed and promoted via policy instruments as well. A literature review showed that national programmes for eco-industrial parks can be found in different parts of the world. In the action programmes and other sustainable consumption and production (SCP) policy documents of the EU, on the other hand, industrial symbioses gain less recognition as a path to enhanced sustainable production. In this article, we consider this and also analyse how the evolution and environmental performance of an industrial symbiosis system centred on a Finnish pulp and paper mill have been affected by SCP policy instruments. With regard to the system forming the subject of the case study, and Finnish industrial systems in general, policy instruments have succeeded in reducing emissions but not in systematically encouraging operators toward symbiosis-like activities. All in all, few studies exist on the overall impact of policy instruments promoting design of eco-industrial parks. It is not self-evident that symbiosis-like production systems would be sustainable in every case, as the background assumptions for political promotion of EIPs suggest. We concluded that industrial symbioses should be analysed and developed on a life cycle basis, with documentation of the real environmental benefits due to efficient resource use and decreased emissions in comparison to standalone production. ISs can then bring eco-competitiveness to companies in relation to SCP tools, such as environmental permits, ecolabels, and future product regulation based on the Ecodesign Directive in Europe. Indirect encouragement of symbiosis through land-use regulation and planning, in such a way that material fluxes between companies are possible both in operations and in financial terms, may prove effective. The same holds for waste policies that encourage increased reuse of a company’s waste by other enterprises.     

Techno policy aspects and socio-economic impacts of eco-industrial networking in the fishery sector: experiences from An Giang Province,Vietnam

Eco-industrial networking is considered as a new approach for businesses to improve their competitiveness, economic viability and human and ecosystem health. A cyclic material flow with alternative usage of all materials in the loop is an essential feature of an eco-industrial network. While eco-industrial networking has been primarily applied on the high-tech sector, this paper attempts to apply the principles on the fishery sector of An Giang, a Vietnamese province in the Mekong River Delta. An Giang Province has its own market share in the trade of Tra and Basa fish. The industries in the value chain of Tra and Basa are in a situation that forces them to improve their competitiveness to retain the market share. It was found that forming an eco-industrial network and recruiting new businesses to utilize all materials in the process provides additional revenue apart from reducing waste disposal concerns. This paper details the current market situation, the issues faced and material flow patterns and presents a feasible eco-industrial network. The results of the study indicate that the eco-industrial network creates positive impacts in terms of increased competitiveness, improved socio-economic conditions and cleaner environment.

Evaluation of innovative municipal solid waste management through urban symbiosis: a case study of Kawasaki

Industrial symbiosis encourages the establishment of a broad eco-industrial network so that more synergy opportunities can be identified. By linking municipal solid waste management (MSWM) with local industries, i.e., urban symbiosis, new symbiotic opportunities can be generated from the geographic proximity of urban and industrial areas, transferring physical resources from urban refuse directly to industrial applications and improving the overall eco-efficiency of the city as a whole. Using a case study of Kawasaki, this paper simulates and evaluates an innovative waste management initiative in Kawasaki by an scenario simulation model based on the LCA approach. Results show that recycling mixed paper, mixed plastics, and organic wastes and utilizing the recycled materials in industrial production will potentially reduce about 69 kt CO₂(e) emissions and 8 kt incineration ashes to be landfilled in 2015. To achieve these outcomes, the total additional cost compared with the current practice is about 1.2 billion JPY.     

Introduction to the special issue on Advances in Life-Cycle Approachesto Business and Resource Management in the Asia-Pacific Region

This special issue of the Journal of Cleaner Production was initiated as a result of the 5th and 6th meetings of the Asia Pacific Roundtable for Sustainable Consumption and Production (APRSCP), which were held in Melbourne, Australia and Hanoi, Vietnam, respectively. A need identified at those meetings was to create another means of communicating the best ideas and papers being presented, to a wider audience. The Asia Pacific region has special development needs given its rapid emergence as a global production hub, but coupled to that are also the rapid social adjustments and shifts in patterns of consumption and production which aren't positive for the environment. This special issue contains eight papers covering the implementation of cleaner production and life cycle principles at the systems and regional planning level. These articles cover urban development, corporate CP programs, supply chain management, eco-industrial networks, and industrial parks, recycling, and understanding the role of human factors in bringing about environmental change.

Assessing the future of small-scale fishery systems in coastal Vietnam and the implications for policy

Our aim in this paper is to examine the future for small-scale fishers and fish producers in the rapidly changing Tam Giang Lagoon in central Vietnam. The analysis shows: (1) the multi-dimensional and linked social, ecological and economic challenges confronting lagoon resource users and government officials, including the possibility that important features of the ecological system have been significantly altered; and (2) the spatial and temporal variation in the lived experience and conditions facing lagoon resource users even in the context of one relatively-bounded physical system. In this context, policy and management interventions need to better reflect social and ecological variability, incorporate local perspectives about the future of small-scale fishing and small producer aquaculture, and acknowledge how individuals simultaneously produce, resist and adapt to change. Key policy responses include the adoption of an integrated fishery (fishing and aquaculture) and coastal systems perspective, clarifying security of access rights to aquatic resources, and building institutional conditions for greater collaboration and learning among resource users and decision makers.
