Abstract

A process for manufacturing poly(3-hydroxybutyrate) (PHB) using Cobetia amphilecti from celery waste was modeled and analyzed, focusing on the technical and economic aspects. The process produced 1871 tonnes/year of PHB from 4397 tonnes/year of mannitol extracted from 52,350 tonnes/year of celery waste. The economic analysis revealed a capital investment of 19.3 million US$, emphasizing equipment costs as a significant portion of the total expenses. The PHB production process has a positive net present value of 2.3 million US$, a 15.7 % return on investment, a payback period of 6.4 years, and an 8.9 % internal rate of return. Profitability analysis indicated a favorable scenario with a total revenue of 10.3 million US$, an actual minimum selling price of 5.5 US$/kg, and the lowest achievable production cost of 4.6 US$/kg. Sensitivity analysis underscored the influence of celery waste pricing, solid loading, and an extractant price for PHB pricing and economic viability.

期刊介绍： Official Journal of the European Federation of Chemical Engineering: Part C FBP aims to be the principal international journal for publication of high quality, original papers in the branches of engineering and science dedicated to the safe processing of biological products. It is the only journal to exploit the synergy between biotechnology, bioprocessing and food engineering. Papers showing how research results can be used in engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in equipment or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of food and bioproducts processing. The journal has a strong emphasis on the interface between engineering and food or bioproducts. Papers that are not likely to be published are those: • Primarily concerned with food formulation • That use experimental design techniques to obtain response surfaces but gain little insight from them • That are empirical and ignore established mechanistic models, e.g., empirical drying curves • That are primarily concerned about sensory evaluation and colour • Concern the extraction, encapsulation and/or antioxidant activity of a specific biological material without providing insight that could be applied to a similar but different material, • Containing only chemical analyses of biological materials.
