Industrial symbiosis networks conventionally provide economic and environmental benefits to participating industries. However, most studies have failed to quantify waste management solutions and identify network connections in addition to methodological variation of assessments. This study provides a comprehensive model to conduct sustainable study of industrial symbiosis, which includes identification of network connections, life cycle assessment of materials, economic assessment, and environmental performance using standard guidelines from the literature. Additionally, a case study of industrial symbiosis network from Sodankylä region of Finland is implemented. Results projected an estimated life cycle cost of €115.20 million. The symbiotic environment would save €6.42 million in waste management cost to the business participants in addition to the projected environmental impact of 0.95 million tonne of CO2, 339.80 tonne of CH4, and 18.20 tonne of N2O. The potential of further cost saving with presented optimal assessment in the current architecture is forecast at €0.63 million every year.

Одним из важных аспектов в системе управления инвестиционными проектами в крупных холдинговых компаниях является финансово-экономическая оценка эффективности проекта, которая должна проводится на всех стадиях жизненного цикла проекта. Использование классических походов к оценке эффективности проекта, основанных на применении статических показателей доходности проекта и динамических показателей доходности, основанных на применении процесса дисконтирования, не достаточно. Как показывает практика, помимо стоимостных критериев, необходимо учитывать и дополнительные эффекты, такие как экологичность проекта, техническую безопасность, клиентоориентированность, повышение качества продукции.В научной статье представлен алгоритм оценки финансово-экономической оценки эффективности инвестиционного проекта по стадиям жизненного цикла. На этапе зарождения идеи предлагается проводить экспертную оценку эффективности инвестиционного проекта на основе чек-листа, на этапе предпроектной проработки и подготовки проекта к реализации необходимо оценивать эффективность проекта на основе DCF-модели и относительных показателей эффективности. На этапе реализации проекта следует проводить постинвестиционный мониторинг ключевых показателей эффективности проекта. Предлагаемый алгоритм позволит своевременный мониторинг и проводить корректирующие действия и повысить эффективность принимаемых управленческих решений в области инвестиционной деятельности компании. One of the important aspects in the investment project management system in large holding companies is the financial and economic assessment of project effectiveness, which should be carried out at all stages of the project life cycle. The use of classical approaches to assessing the effectiveness of a project based on the use of static indicators of project profitability and dynamic indicators of profitability based on the application of the discount process is not enough. As practice shows, in addition to cost criteria, it is necessary to take into account additional effects, as the project is environmentally friendly, technical safety, customer focus, improving product quality.The scientific article presents an algorithm for evaluating the financial and economic evaluation of the effectiveness of an investment project by the stages of the life cycle. At the stage of generating the idea, it is proposed to conduct an expert assessment of the effectiveness of the investment project on the basis of a checklist; at the stage of pre-project study and preparation of the project for implementation, it is necessary to evaluate the effectiveness of the project based on the DCF model and relative performance indicators. At the project implementation stage, post-investment monitoring of key project performance indicators should be carried out. The proposed algorithm will allow timely monitoring and corrective actions and increase the effectiveness of managerial decisions in the field of investment activities of the company.

In the Development of construction materials Sustainable use of natural resources has become a necessity in India. In this project work, an LCA study is carry out for an AAC block production for environmental assessment. In addition to the LCA, the Life Cycle Cost (LCC) analysis is also applied for economic assessment. The LCA is performed according to ISO 14040. Firstly, a cradle to gate LCA method performed for one meter cube of Autoclaved Aerated Concrete Block. The LCCA method include in the OpenLCA software which is choose to calculate impact categories i.e. abiotic depletion, global warming potential, acidification potential, eutrophication potential, Eco toxicity, ozone depletion potential and photochemical oxidation potential. The last few decades, several approaches have been developed by agencies and institutions for Bricks Life Cycle Cost Analysis (LCCA). The LCC analysis was performed by developing a price model for internal and external cost categories within the software.
