Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

This book examines the key aspects that will define future sustainable energy systems: energy supply, energy storage, security and limited environmental impacts. It clearly explains the need for an integrated engineering approach to sustainable energies, based on mathematical, biogeophysical, and engineering arguments. Resilient and efficient alternatives are compared to non-sustainable options. This book results from the collaboration of 50 international contributors.

The present investigation was oriented to the economic-financial analysis to determine the viability of the production and commercialization of fruits native to the Amazon in syrup in the city of Puyo. To base the work, the operation of the plant where the place of production was established was analyzed; being a comfortable, cozy place with a storage room for the raw material and the elaborated product. In addition, an economic analysis was conducted where reliable accounting data was obtained to determine the economic feasibility of the investment; Also, the income and expenses of the production of fruits in syrup projected to five years were determined. In the cash flow, the operational movements were made known daily and finally the financial statements were projected. Once the accounting and budgetary data was obtained, the financial analysis was carried out, where the economic feasibility of the investment was obtained taking into account the value of the money over time. For this, the net present value was 23,186.73 and an internal rate was calculated. of return of 27%. This showed that the investment is acceptable, and the capital recovery will be within three years and eight months approximately. After the analysis, it was concluded that the research project has economic feasibility for the implementation of the business, which would imply being the pioneers in the launch of this product in the domestic market. Neutrosophic numbers was used to represent indeterminacy.
