Comparative economic assessment of centralized and decentralized cordyceps production using shipping containers with associated energy use and GHG emissions

Mahsa Alian, Sunil P. Dhoubhadel, Venkatesh Balan

Cordyceps militaris is a high-value medicinal mushroom known for its bioactive compounds, including cordycepin and polysaccharides, which have driven demand for scalable and economically efficient cultivation systems. This study presents an integrated techno-economic analysis (TEA) of Cordyceps production in modular shipping-container units under two operational strategies: (i) a centralized system with on-site substrate and spawn preparation, and (ii) a decentralized system relying on commercially produced spawn at a single grow-only site. Red rice was used as the cultivation substrate at two production scales (50 and 100 lb/day) and evaluated using a five-year financial model that incorporated capital expenditure (CapEx), operating expenditure (OpEx), revenue, net cash flows, discounted cash flows, and net present value (NPV). The model assumed 80% debt and 20% equity financing, a WACC of 6.48%, and a 30% corporate tax rate. GHG emissions were quantified within a farm-gate boundary encompassing electricity consumption, CO 2 from mushroom respiration, and raw material transportation. Centralized systems required higher initial CapEx ($212,232 and $375,408) but benefited from substantially lower raw-material costs, resulting in superior operating margins and annual cash flows. In contrast, decentralized systems incurred two-to three-fold higher substrate-related costs, which constrained profitability despite lower upfront capital requirements. As a result, centralized systems achieved significantly higher NPVs and shorter payback. Sensitivity analysis confirmed that the selling price and biological efficiency are the dominant drivers of NPV, while the electricity price has minimal influence across all scenarios. Centralized container-based production offers a more economically viable and scalable pathway for commercial Cordyceps cultivation.

Block Chain based Remicon Quality Management

Seungwon Cho, Doyeop Lee, Chansik Park

Block Chain based Remicon Quality Management Seungwon Cho, Doyeop Lee and Chansik Park Pages 1098-1105 (2020 Proceedings of the 37th ISARC, Kitakyushu, Japan, ISBN 978-952-94-3634-7, ISSN 2413-5844) Abstract: Remicon, an important material constituting the structure of a building, needs an efficient quality management system throughout the entire process from production to delivery, including production management, shipment-transport management, and delivery management, to ensure the required performance by the contractor. Nowadays Remicon factories becoming smart factories and automated form for systematic and accurate management throughout the entire process from production to delivery, including product management, manufacturing facility management, transportation management and quality management based on advanced IT technology and computerization. However, data generated from sensor technology, big data processing technology, and SCM system, which are currently applied to the Remicon factory, are managed through single server management system. A single server has a high possibility of forgery and loss of data, which makes it less reliable for quality management of Remicon. In this study, we propose a Remicon quality management system based on the hyper-ledger fabric, a private block chain. This is a system that can digitally generate information that needs to be verified by the quality manager to secure the quality of Remicon at each stage of ?mixing-transport-delivery' and share it to all nodes participating in the block chain network to guarantee data reliability. In addition, the Dapp (distributed application) of each node has different ledger access rights. So Remicon manufacturers belonging to different channels do not share sensitive information, but contractors and government can view the status of all Remicon quality management at the construction site.
