Abstract
Bio-based and biodegradable plastics: An annotated selection of World Wide Web sites relevant to the topics in microbial biotechnology.
Highlights
The point of reference used in the uncertainty assessment of life cycle assessment (LCA) results is the environmental evaluation of a life cycle, treated as a certain measurement technique based on a given methodology [1]
We have achieved the objective of the paper by proposing a method for the evaluation of uncertainty and precision of life cycle analysis (LCA) results based on the data quality indicator (DQI) semi-quantitative approach, stochastic modelling and sensitivity analysis
The material used for producing the pre-form (PLA) represents the input which has the greatest effect on the result of environmental impacts of the PLA bottle shaping process
Summary
The point of reference used in the uncertainty assessment of life cycle assessment (LCA) results is the environmental evaluation of a life cycle, treated as a certain measurement technique based on a given methodology [1]. Its application leads to the “measurement” of two basic elements: environmental aspects that occur in the life cycles of products and subsequent environmental impacts [1–4]. Never can a single value without an uncertainty range represent the true value of an environmental impact because each measurement has uncertainty [5,6]. The process of producing bottles made of polylactide adopted in this paper focuses on the assessment of six technological operations, and concerns primarily the consumption of electricity, water and CO2 emissions. The implementation of biodegradable polymers into the production process is the result of increasing amounts of residual polymer waste. Plastics were produced to obtain durable, environmentally sensitive products. A change in strategy seeking alternative sources of materials has resulted in the development
