Composite Material Recycling Technology—State-of-the-Art and Sustainable Development for the 2020s
2021
Recently, significant events took place that added immensely to the sociotechnical pressure for developing sustainable composite recycling solutions, namely (1) a ban on composite landfilling in Germany in 2009, (2) the first major wave of composite wind turbines reaching their End-of-Life (EoL) and being decommissioned in 2019–2020, (3) the acceleration of aircraft decommissioning due to the COVID-19 pandemic, and (4) the increase of composites in mass production cars, thanks to the development of high volume technologies based on thermoplastic composites. Such sociotechnical pressure will only grow in the upcoming decade of 2020s as other countries are to follow Germany by limiting and ba…
Economic valuation of environmental benefits of removing pharmaceutical and personal care products from WWTP effluents by ozonation.
2013
Continuous release of pharmaceutical and personal care products (PPCPs) present in effluents from wastewater treatment plants (WWTPs) is nowadays leading to the adoption of specific measures within the framework of the Directive 2000/60/EC (Water Framework Directive). The ozonation process, normally employed for drinking water production, has also proven its potential to eliminate PPCPs from secondary effluents in spite of their low concentrations. However, there is a significant drawback related with the costs associated with its implementation. This lack of studies is especially pronounced regarding the economic valuation of the environmental benefits associated to avoid the discharge of …
Wastewater treatment and reclamation : A review of pulp and paper industry practices and opportunities
2016
The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with cost-effective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which…
A content analysis on family firms' association annual questionnaire
2010
The aim of this paper is to analyze the content of a questionnaire that is used in order to conduct a Finnish Family Firms’ Association’s annual barometer for its members. The content of the questionnaire is reflected to a relevant theory and compared with two other fairly similar questionnaires. Based on the analysis, reflections, and comparisons some suggestions for questionnaire modification are presented. The research question concerns what kind of data may be essential to measure among Finnish family firms. This paper aims at enhancing the Finnish Family Firms’ Association to conduct a questionnaire that may allow even deeper understanding on the situation and position of family busine…
Banca ética y banca cooperativa. Un análisis comparativo a través del estudio de Caixa Popular y de Fiare Banca Ética
2017
Los bancos sociales representan en la actualidad una alternativa a la banca convencional, sobre todo para aquellos clientes que demandan un consumo socialmente responsable. La banca social está formada por dos tipos diferentes de entidades de crédito: los bancos cooperativos y los bancos éticos. Los primeros desarrollan su actividad desde hace ya más de un siglo a través de un modelo de banca de proximidad enfocada al territorio. Los segundos llevan tres décadas aproximadamente de funcionamiento, dirigiéndose a la realización de inversiones socialmente responsables (proyectos sociales y medioambientales). En el presente trabajo se analizan las similitudes y diferencias entre ambos modelos d…
Simultaneous Separation of Antioxidants and Carbohydrates From Food Wastes Using Aqueous Biphasic Systems Formed by Cholinium-Derived Ionic Liquids
2019
project CICECO-Aveiro Institute of Materials, UID/CTM/50011/2019. Associate Laboratory for Green Chemistry-LAQV, FCT Ref. UID/QUI/50006/2019. POCI-01-0145-FEDER-016403. Investigator FCT project IF/00621/2015. Programa Mais Centro under project CENTRO-07-ST24-FEDER-002008. COMPETE: PEst-C/SAU/UI0709/2011. The food industry produces significant amounts of waste, many of them rich in valuable compounds that could be recovered and reused in the framework of circular economy. The development of sustainable and cost-effective technologies to recover these value added compounds will contribute to a significant decrease of the environmental footprint and economic burden of this industry sector. Acc…
Solar radiation as a prospective energy source for green and economic processes in the food industry: From waste biomass valorization to dehydration,…
2019
International audience; Solar energy has recently attracted the attention of both industry and academia, to be used as a source of clean energy for green production of various products such as food-related commodities. This review aims to explore the applicability of this green energy source for extraction of valuable components (e.g., bioactive compounds and essential oils) from plant materials and waste biomass, dehydration of plant materials, water recovery through desalination, decontamination, cooking, and baking of agri-food products. According to the literature, concentrated solar power systems (CSP) have been successfully employed for bioactive compounds (e.g. essential oils) extrac…
Effect of sodium borohydride and hydrogen peroxide pretreatments on soda pulping of sugar maple (Acer saccharum)
2021
For recovering value-added wood-based organic material prior to delignification, sodium borohydride (NaBH4) and hydrogen peroxide (H2O2) pretreatments under alkaline conditions were performed before soda pulping of sugar maple (Acer saccharum) chips with sodium hydroxide (NaOH). In this investigation, it was determined whether the pulp yield could be increased by partly stabilizing the hemicelluloses by these pretreatments, and simultaneously obtains lower pulp kappa numbers. The results indicated that when aiming to the same kappa numbers (i.e., kappa numbers 14.3-20.5), roughly 3% higher pulp yield could be achieved if the chips were pretreated with alkaline 0.5% NaBH4 solutions, compared…
Ecosocial Innovations and Their Capacity to Integrate Ecological, Economic and Social Sustainability Transition
2019
The article contributes to sustainability transition research by indicating the significance of transformative grassroots innovations in the context of social work research. We introduce the integrative concept of ecosocial innovation in order to demonstrate how grassroots innovations can successfully combine social, ecological and economic aspects of a sustainability transition. By ecosocial innovations, we refer to social innovations with a strong ecological orientation (e.g., recycling workshops, urban gardening, participatory unemployment projects and new local economies). The data consists of 50 examples of ecosocial innovations in Finland, Italy, Germany, Belgium and the UK. We invest…
Road project opportunity costs subject to a regional constraint on greenhouse gas emissions
2012
Abstract France has constrained the Aquitaine region to set up a climate plan to avoid an emission of 2883 ktCO 2 eq for the period 2007–2013. In parallel, the region has decided to carry out the construction of road infrastructures in order to avoid very high congestion costs. Those road projects will involve an increase in greenhouse gas (GHG) emissions during that period. In the present context of strong sustainability, all emissions (direct and indirect) generated by those projects should be offset. At the regional level, the offsetting of GHG emissions is usually carried out by implementing carbon sequestration projects or projects that reduce energy demand. This paper aims at determin…
