Life cycle assessment of an industrial symbiosis based on energy recovery from dried sludge and used oil

Recovering energy from wastes is a useful strategy for integrated waste and energy management in an eco-industrial park (EIP) and gives promising reduction of wastes, total energy consumption and operation cost. In Jinqiao EIP, Pudong New Area, Shanghai, an industrial symbiosis, based on the energy recovery from municipal sewage sludge and re-refined oil, was proposed in the central heat-supplying company of Jinqiao EIP. It is expected that hot off-gas or part of the steam from the central heat-supplying company could be used for sludge drying and used oil re-refining while the dried sludge and refined oil can be partial substitution for fossil fuel. For the purpose of assessing the environmental performance of this industrial symbiosis, life cycle assessment (LCA) was used and different scenarios were set up in this study to evaluate the Global warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP), Human toxicity air (HTA) and Total Environmental Impact Potential (TEIP) of the system. Results indicate that when the substitute ratio of coal by sludge is 14%, the proposed industrial symbiosis has the least environmental impact. Compared with the current situation (sludge is landfilled), co-combustion of dried sludge and re-refined oil with coal at optimal scale will release less CO₂, CH₄, NO_x, N₂O and CO, but more SO₂, H₂S, NH₃, HCl, polycyclic aromatic hydrocarbons (PAHs), non-methane volatile organic compounds (NMVOC) and heavy metals.

A Systems Based Framework to Examine The Multi-contextural Application of the Sustainability Concept

A conceptual framework is generated through systems principles to explain sustainability’s wide diversity of interpretation and contextual application. Sustainability is reduced to a literal interpretation as the ability to sustain, and then expressed in simple systems as the ability of one system to sustain another system over time. This reinforces the importance of time in the sustainability debate, and suggests the concept can be legitimately applied to timeframes that have absolute limits. The framework is expanded to complex systems as the changing ability of one or many systems to sustain the changing requirements of one or many systems, over time. This accommodates multiple relations and system dynamics, and hints at the extraordinary complexity encompassed by the sustainability concept. Practical implications relate to the evolving meaning of sustainability, the need for continual change to remain sustainable, and that the sustainability concept can be validly applied to virtually any context or situation that exhibits a dimension of continuity. Derived criteria useful for clarifying contextual applications of sustainability include stating the how, what, why, who and for how long of sustainability, along with indicating the most appropriate hierarchical tier at which the concept is being applied.

"城中村"改造的效益分析

我国城市化进程的快速发展、城乡二元管理体制和土地二元所有制结构导致了"城中村"的形成.为落实科学发展观,促进城市全面、协调发展,必须对"城中村"加强管理,完善基础设施,改善卫生条件,规范土地的使用.通过"城中村"的改造能提高城市土地利用率,改善居住环境、投资环境和生态环境,更好地建设资源节约型、环境友好型社会.     

我国绿色物流的发展现状和应对措施

所谓绿色物流,就是以降低对环境的污染、减少资源消耗为目标的物流活动。但是,绿色物流的理念才刚刚传入我国,对政府和企业而言都还是一个全新的话题,不少企业对其重要性还缺乏认识。对此,政府应该根据5R原则对企业进行规制与政策激励,加强企业的环境自律和消费者的绿色理念宣传,把绿色理念的传播贯穿全社会。
