Economic feasibility study for new technological alternatives in wastewater treatment processes: a review

2012

The concept of sustainability involves the integration of economic, environmental, and social aspects and this also applies in the field of wastewater treatment. Economic feasibility studies are a key tool for selecting the most appropriate option from a set of technological proposals. Moreover, these studies are needed to assess the viability of transferring new technologies from pilot-scale to full-scale. In traditional economic feasibility studies, the benefits that have no market price, such as environmental benefits, are not considered and are therefore underestimated. To overcome this limitation, we propose a new methodology to assess the economic viability of wastewater treatment tec…

Hunting for valuables from landfills and assessing their market opportunities A case study with Kudjape landfill in Estonia

2017

Landfill mining is an alternative technology that merges the ideas of material recycling and sustainable waste management. This paper reports a case study to estimate the value of landfilled materials and their respective market opportunities, based on a full-scale landfill mining project in Estonia. During the project, a dump site (Kudjape, Estonia) was excavated with the main objectives of extracting soil-like final cover material with the function of methane degradation. In total, about 57,777 m3 of waste was processed, particularly the uppermost 10-year layer of waste. Manual sorting was performed in four test pits to determine the detailed composition of wastes. 11,610 kg of waste was…

Comment: What is Alternative Technology? A Reply to Professor Stanley Carpenter

1983

Modern man is dissatisfied with the technology we have and would replace it with another. Three very different reasons are given for this. I will divide my treatment of them under three headings, listing the reason in each case together with a reply.
