How does technology pathway choice influence economic viability and environmental impacts of lignocellulosic biorefineries?

This study conducted a questionnaire-led survey to explore the financial feasibility and socio-environmental impacts of stand-alone solar home systems (SHS) through stratified random sampling. Based on the above consideration, fifteen cases of studies of various watt peak (Wp) capacities have been investigated to evaluate the economic viability of solar home systems. The results revealed that most of the cases have positive net present value (NPV) and low payback periods, with an internal rate of return (IRR) value ranging from 16% to 131%, which signifies a high rate of investment exchange. Solar home systems are economically profitable for micro-enterprises and households with low-income generation activities as opposed to the households using it only for lighting. The study found that solar home systems with a capacity above 30 Wp are the most economically viable option, which can also avoid 6.15 to 7.34 tonnes of CO2 emissions during the 20 years of life-cycle, while providing different applications including lighting, recreation, information, health, and economic benefits.

Definition Of

Purpose – This study’s main objective is to verify if there is a relation between proactivity and technological protection in the environmental performance of the ventures in this segment. And check if there is economic feasibility to produce interlocking concrete paving blocks with the addition of rubber, as well as the certification of the product as ecologically friendly.Design/methodology/approach – The study is based on the methodologies shown by Dickel (2017), questionnaire and variables, and Bertolini (2009), economic viability for the manufacture of ecologically friendly products.Findings – As a result, the study confirms the association between technological protection and proactivity in environmental performance, as well as the economic viability for the offer of the interlocking concrete paving product with ecological certification.Originality/value – Civil construction occupies a prominent position, accounting for a significant portion of Brazil's Gross Domestic Product (GDP), as well as being the largest employer industry in the country. It is also recognized as having significant environmental impacts in the conduct of its activities. However, the search for sustainability has been a mobilizing element in the definition of corporate strategies, companies have been seeking more and more actions that are economically viable, respecting environmental and social aspects.
