Sustainable polymers derived from biomass have been considered as promising candidates to reduce the dependency on fossil based polymers. In this study, a conceptual process design was conducted for citrus waste derived biopolymer production with energy co-generation, and its eco-friendliness was evaluated through life cycle assessment by comparison against a petroleum derived polymer production process. Based on the current research, two original conclusions were proposed. The first one is that energy-efficient separation techniques are of critical importance for the design of eco-friendly chemical processes. Only focusing on the use of sustainable feedstocks with high conversion reactions cannot guarantee an environmentally-friendly final product. The second one is that biomass should be considered not only as a raw material, but more importantly, as an energy source for the sustainable synthesis of biochemicals. In other words, a sustainable process should be designed such that a portion of biomass is used to provide clean energy for process operation, with the rest converted for product generation.

Biomass is a promising feedstock for the production of sustainable biopolymers, which could offer a significant reduction of the adverse environmental impacts associated with conventional petroleum-based polymers. To further evaluate their potential, this study investigated the environmental impacts associated with the production of the newly proposed biopolymer polylimonene carbonate. Different feedstocks (citrus waste and microalgae) were selected and a conceptual process design from limonene oxidation to polymer synthesis was completed. Using life cycle assessment, the potential for energy integration and the contributions of individual process sections on the overall process environmental impacts were thoroughly analysed. The results showed, that sustainable polylimonene carbonate synthesis was limited by the use of tert-butyl hydroperoxide as the limonene oxidation agent and consequently, a more environmentally-friendly and energy-efficient limonene oxidation method should be developed. Based on the economic analysis, the polymer cost was estimated to range from $1.36 to $1.51 kg −1 , comparable to the costs of petrol-based polystyrene ($1.2 to $1.6 kg −1 ). Moreover, this study found that both feedstock selection and the biowaste treatment method have significant effects on the process environmental impacts, and a carbon negative process was achieved when applying the waste biomass for electricity generation. Therefore, it was concluded that future process designs should combine polymer production with the co-generation of energy from waste biomass.

Biodiesel produced from microalgae has been extensively studied due to its potentially outstanding advantages over traditional transportation fuels. In order to facilitate its industrialization and improve the process profitability, it is vital to construct highly accurate models capable of predicting the complex behavior of the investigated biosystem for process optimization and control, which forms the current research goal. Three original contributions are described in this paper. Firstly, a dynamic model is constructed to simulate the complicated effect of light intensity, nutrient supply and light attenuation on both biomass growth and biolipid production. Secondly, chlorophyll fluorescence, an instantly measurable variable and indicator of photosynthetic activity, is embedded into the model to monitor and update model accuracy especially for the purpose of future process optimal control, and its correlation between intracellular nitrogen content is quantified, which to the best of our knowledge has never been addressed so far. Thirdly, a thorough experimental verification is conducted under different scenarios including both continuous illumination and light/dark cycle conditions to testify the model predictive capability particularly for long-term operation, and it is concluded that the current model is characterized by a high level of predictive capability. Based on the model, the optimal light intensity for algal biomass growth and lipid synthesis is estimated. This work, therefore, paves the way to forward future process design and real-time optimization.

© 2018 Elsevier B.V. Biomass derived polymers are considered as promising candidates to replace petroleum based polymers due to their potential environmental friendliness. To facilitate their application, in this study, a newly proposed biopolymer, polylimonene carbonate, was chosen as the representative to investigate the environmental impacts of the biopolymer production process. Different feedstocks (citrus waste and microalgae) were selected and a comprehensive process design from limonene oxidation to polymer synthesis was completed. Through life cycle assessment, effects of biomass treatment methods, energy integration, and use of solvents on the process environmental impacts were thoroughly discussed. It was found that for sustainable polylimonene carbonate synthesis, a more environmentally-friendly and energy-efficient limonene oxidation method should be developed. Based on the economic analysis, the polymer's cost was estimated to be around 1.36 to 1.51 $/kg, indicating its great potential as a substitute for petrol-based polystyrene. Moreover, this study found that both feedstock selection and biowaste treatment method significantly affect the process environmental impacts, and a carbon negative biopolymer can be achieved when the remaining waste is used for energy generation. Therefore, a new concept that considers CO2 as an efficient solar energy carrier for future sustainable process design is proposed in this study.

Zhang D, del Rio-Chanona EA, 2018, A Bilevel Programming Approach for the Dynamic Optimization of Cyanobacterial C-phycocyanin Production under Uncertainty, Computer Aided Chemical Engineering, Pages: 535-540

© 2018 Elsevier B.V. C-phycocyanin is a high-value bioproduct synthesized by cyanobacterium Arthrospira platensis with a significant global market demand given its applications in the pharmaceutical, food and colorant industries. Unfortunately, its biosynthesis is currently characterized by low productivity and large uncertainty during the production process. High variability and unreliable expectations on product yields substantially hinder the industrialization of microorganism derived biochemicals as they present a risk to the profitability and safety of the underlying systems. Therefore, in this work, we propose a robust optimization approach to determine the lower and upper product yield expectations for the sustainable production of C-phycocyanin. Kinetic modeling is adopted in this study as a tool for fast prototyping, prediction and optimization of chemical and biochemical processes. On the upside, parameters in bioprocess kinetic models are used as a simplification of the complex metabolic networks to enable the simulation, design and control of the process. On the downside, this conglomeration of parameters may result in significant model uncertainty. To address this challenge, we formulate a bilevel max-min optimization problem to obtain the worst-case scenario of our system given the uncertainty on the model parameters. By constructing parameter confidence ellipsoids, we determined the feasible region along which the parameters can minimize the system's performance, while nutrient and light controls are used to maximize the biorenewable production. The inner minimization problem is embedded by means of the optimality conditions into the upper maximization problem and hence both are solved simultaneously. Through this approach, we determined pessimistic and optimistic scenarios for the bioproduction of C-phycocyanin and hence compute reliable expectations on the yield and profit of the process.

del Rio-Chanona EA, Zhang D, Shah N, 2017, Sustainable biopolymer synthesis via superstructure and multiobjective optimization, AIChE Journal, Vol: 64, Pages: 91-103, ISSN: 0001-1541

Sustainable polymers derived from biomass have great potential to replace petrochemical based polymers and fulfill the ever-increasing market demand. To facilitate their industrialization, in this research, a comprehensive superstructure reaction network comprising a large number of reaction pathways from biomass to both commercialized and newly proposed polymers is constructed. To consider economic performance and environmental impact simultaneously, both process profit and green chemistry metrics are embedded into the multiobjective optimization framework, and MINLP is used to enable the effective selection of promising biopolymer candidates. Through this proposed approach, this study identifies the best biopolymer candidates and their most profitable and environmentally friendly synthesis routes under different scenarios. Moreover, the stability of optimization results regarding the price of raw materials and polymers and the effect of process scale on the investment cost are discussed in detail. These results, therefore, pave the way for future research on the production of sustainable biopolymers.

Lutein is a high-value bioproduct synthesized by microalga Desmodesmus sp. It has great potential for the food, cosmetics, and pharmaceutical industries. However, in order to enhance its productivity and to fulfil its ever-increasing global market demand, it is vital to construct accurate models capable of simulating the entire behavior of the complicated dynamics of the underlying biosystem. To this aim, in this study two highly robust artificial neural networks (ANNs) are designed for the first time. Contrary to conventional ANNs, these networks model the rate of change of the dynamic system, which makes them highly relevant in practice. Different strategies are incorporated into the current research to guarantee the accuracy of the constructed models, which include determining the optimal network structure through a hyper-parameter selection framework, generating significant amounts of artificial data sets by embedding random noise of appropriate size, and rescaling model inputs through standardization. Based on experimental verification, the high accuracy and great predictive power of the current models for long-term dynamic bioprocess simulation in both real-time and offline frameworks are thoroughly demonstrated. This research, therefore, paves the way to significantly facilitate the future investigation of lutein bioproduction process control and optimization. In addition, the model construction strategy developed in this research has great potential to be directly applied to other bioprocesses.

Sustainable polymers derived from biomass have been extensively investigated to replace petroleum-based polymers and fulfill the ever-increasing market demand. Because of the diversity of biomass and polymer categories, there exists a large number of synthesis routes from biomass to polymers. However, their productive and economic potentials have never been evaluated. Therefore, in this study, a comprehensive reaction network covering the synthesis of 20 polymers, including both newly proposed biopolymers and traditional polymers, is constructed to resolve this challenge for the first time. Through the network, over 100 synthesis pathways are screened to identify the most promising biopolymers. Three original contributions are concluded. First, from a carbon point of view, polyethylene and 1,4-cyclohexadiene-based polymers are found to be the best petroleum-based polymer and newly proposed biopolymers that can be produced from biomass, respectively, because of their highest carbon recovery efficiency of ∼70%. Second, an external hydrogen supply is vital to guarantee the high yield of biopolymer, because, without enough hydrogen, biopolymer productivity can be reduced by half. Third, through sensitivity analysis, the current biopolymer ranking is verified to be stable, subject to a moderate change of reaction selectivities and hydrogen supply. Therefore, this study provides a clear direction for future biopolymer research.

Artificial neural networks have been widely applied in bioprocess simulation and control due to their advantageous properties. However, their feasibility in long-term photo-production process modeling and prediction as well as their efficiency on process optimization have not been well studied so far. In the current study, an artificial neural network was constructed to simulate a 15-day fed-batch process for cyanobacterial C-phycocyanin production, which to the best of our knowledge has never been conducted. To guarantee the accuracy of artificial neural network, two strategies were implemented. The first strategy is to generate artificial data sets by adding random noise to the original data set, and the second is to choose the change of state variables as training data output. In addition, the first strategy showed the distinctive advantage of reducing the experimental effort in generating training data. By comparing with current experimental results, it is concluded that both strategies give the network great modeling and predictive power to estimate the entire fed-batch process performance, even when few original experimental data are supplied. Furthermore, by optimizing the operating conditions of a 12-day fed-batch process, a significant increase of 85.6% on C-phycocyanin production was achieved compared to previous work, which suggests the high efficiency of artificial neural network on process optimization.

Haematococcus pluvialis is a green algae with the great potential to generate natural astaxanthin. In the current study, dynamic models are proposed to simulate effects of light intensity, light attenuation, temperature and nitrogen quota on cell growth and astaxanthin production in both suspended and attached photobioreactors, which to the best of our knowledge has not been addressed before. Based on the current models, optimal temperatures for algal growth and astaxanthin accumulation are identified. Cell absorption is found to be the primary factor causing light attenuation in the suspended reactor. In this reactor, astaxanthin accumulation is limited by the low local light intensity due to light attenuation during the initial operation period, but almost independent from that once it is close to the maximum value. Compared to the suspended reactor, light attenuation in the attached reactor is much reduced and biomass growth is remarkably enhanced, which suggests that the attached reactor is a better choice if the process aims for biomass cultivation. However, the well-mixed culture in the suspended reactor can push most cells toward astaxanthin production; while the attached reactor has the potential to prevent the accumulation of astaxanthin in the bottom algae. Therefore, the suspended photobioreactor should be selected if the process target is astaxanthin production.
