“…Uncertainty analyses of cellulosic thermochemical biorefineries in the open literature employ both triangular and normal distributions to model TCI uncertainty. In the case of triangular distributions, the deterministic point estimate TCI calculated by the TEA serves as the most likely value while the minimum and maximum values are derived from the expected accuracy range of the capital cost estimation methodology (generally ±30%), resulting in distributions that are both symmetrical and unbiased.…”

This analysis quantifi es the impact of capital cost estimation methodologies and probability distributions on the 20-year net present values (NPV) of six thermochemical cellulosic biofuel pathways. It reviews the methodologies and distributions employed in the open literature, and compares the latter with those reported for existing energy projects. A sensitivity analysis calculates the impact of methodology choice on the NPV of each pathway scenario and an uncertainty analysis calculates the impact of probability distribution choice on the same. The sensitivity analysis fi nds that the choice of pessimistic or optimistic estimation methodology changes NPV by up to $300 million. The uncertainty analysis fi nds that the representation of capital cost by asymmetrical probability distributions increases the standard deviations of the 20-year NPV cumulative distribution functions by up to 35% relative to symmetrical distributions. Finally, recommendations are given to improve capital cost calculations in cellulosic biofuel techno-economic analyses.

“…According to [14] the NPV is the best criterion for selecting or rejecting an investment, either industrial or financial. By using the NPV the expected profit is estimated using today's value of current and future cash flows generated by the AC production plant during a certain time period using a predetermined discount rate [15]. The NPV formula is given in Eq.…”

ABSTRACTOne of the top strategic objectives and research areas in Europe is recovering wood from processing and end of life products. However, there are still several 'contaminated' wood products that are not or only partly reused/recycled. Particle board waste which is contaminated with aminoplasts is one of these products. In addition, a considerable amount of aminoplast waste resinis produced for the production of particle board that cannot be re-used or recycled. The chemical properties of these wastes (high nitrogen content of 5.9 wt% and 54.1 wt% for particle board and melamine formaldehyde respectively) make them ideal precursors for the production of nitrogenised activated carbon. The profitability of the produced activated carbon is investigated by calculating the net present value, the minimum selling price and performing a Monte Carlo sensitivity analysis. Encouraging results for a profitable production are obtained even though the current assumptions start from a rather pessimistic scenario.

With the threat of ‘white pollution’, the large‐scale production and application of biodegradable plastics have become crucial. Poly‐3‐hydroxybutyrate (PHB) is the simplest and most used member of the polyhydroxyalkanoate family, with a uniform C4 structural unit (C4H6O2). To reduce the impact of PHB on waste treatment, various recycling strategies have been developed for the tailored conversion of PHB to targeted chemicals and fuels. Given the special structural unit, PHB and its plastic forms have the potential to serve as a sustainable feedstock for producing a series of value‐added chemicals and fuels, including (i) crotonic acid via pyrolysis, (ii) (R)‐β‐hydroxybutyric acid via hydrolysis, (iii) propylene via depolymerization and decarboxylation, (iv) liquid fuels via deoxygenation and oligomerization, (v) n‐biobutanol via catalytic hydrogenolysis, (vi) methyl crotonate via thermolysis and esterification, (vii) (R)‐3‐hydroxybutyrate methyl ester via catalytic methanolysis, and (viii) β‐aminobutyric acid via ammonolysis. This review article provides a systematic review focusing on the reaction pathways, primary applications and market potential of the target products, and the pros and cons of current bio‐refineries in comparison with conventional petroleum refineries. The thermochemical processes developed for PHB degradation and polypropylene (a typical petroleum‐derived plastic to be replaced by PHB) are also comprehensively evaluated to reveal the future opportunities and challenges of PHB's broad‐scale production and utilization. PHB‐derived chemicals and fuels have a mature market already, and it is confirmed that the tailored valorization of PHB is a promising pathway to expand the market and gain more environmental and energy benefits. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
