以某工业废水为处理对象，对混合菌种PHA(MC)和沼气生产进行了生命周期评价和经济分析。内部收益率(IRR)和不可再生的CO(2)eq排放量被用来量化财务可行性和环境影响。对于特定的工业废水，PHA(MC)比沼气生产更可取。与纯培养生产PHA相比，PHA(MC)在经济上也很有吸引力。两种PHA生产工艺对环境的影响相似，明显低于HDPE生产。PHA(MC)工艺有很大的优化潜力，因为财务和环境成本主要是由于下游加工的能源消耗。在本工作所使用的条件下，PHA(MC)被证明是一种可行的生物聚合物生产工艺和一种有效的工业废水处理技术。这是此类研究的第一次，对PHA(MC)过程提供了有价值的见解。(C)2007爱思唯尔有限公司。保留所有权利。
A life cycle assessment and financial analysis of mixed culture PHA (PHA(MC)) and biogas production was undertaken based on treating an industrial wastewater. Internal rate of return (IRR) and non-renewable CO(2)eq emissions were used to quantify financial viability and environmental impact. PHA(MC) was preferable to biogas production for treating the specified industrial effluent. PHA(MC) was also financially attractive in comparison to pure culture PHA production. Both PHA production processes had similar environmental impacts that were significantly lower than HDPE production. A large potential for optimisation exists for the PHA(MC) process as financial and environmental costs were primarily due to energy use for downstream processing. Under the conditions used in this work PHA(MC) was shown to be a viable biopolymer production process and an effective industrial wastewater treatment technology. This is the first study of its kind and provides valuable insight into the PHA(MC) process. (c) 2007 Elsevier Ltd. All rights reserved.
