A Comparative Analysis of the Social Performance of Global and Local Berry Supply Chains

2016

The goal of this paper is twofold: to comparatively analyze the social performance of global and local berry supply chains and to explore the ways in which the social dimension is embedded in the overall performance of food supply chains. To achieve this goal, the social performance of five global and local food supply chains in two countries are analyzed: wild blueberry supply chains in Latvia and cultivated raspberry supply chains in Serbia. The study addresses two research questions: (1) What is the social performance of the local and global supply chains? (2) How can references to context help improve understanding of the social dimension and social performance of food supply chains? To…

Charakterystyka Palczatki Gerarda (Andropogon gerardi) jako rośliny energetycznej

2017

Celem przeprowadzonej analizy jest charakterystyka palczatki Gerarda jako rośliny energetycznej. Jest to trawa preriowa fotosyntezy typu C4, która nie jest popularnym gatunkiem w Polsce. Artykuł ma charakter przeglądowy i niniejsze opracowanie dotyczące Andropogon gerardi ma na celu zaprezentowanie możliwości jej przydatności w polskich warunkach środowiskowych jako biomasy do produkcji bioenergii na podstawie doniesień z literatury. Powolne tempo wzrostu po okresie zimowym oraz łatwość zachwaszczania plantacji powoduje, że Andropogon gerardi stanowi mało opłacalną roślinę energetyczną w warunkach polskich. Dodatkowo, zostały porównane koszty założenia plantacji w stosunku do wierzby krzewi…

Willingness to Adopt Biochar in Agriculture: The Producer’s Perspective

2017

Most research on biochar has focused either on the mechanistic or the biophysical aspects, and there has been relatively little research into the social applicability and acceptance of biochar as a soil enhancer in agriculture. However, whether to adopt biochar in their practice is ultimately the farmers’ decision, and their willingness to do so is crucial. Here, we show the producer’s perspective on adopting biochar, using Polish farmers as a case study. Poland is an interesting case study because biochar has only recently attracted the attention of researchers, entrepreneurs, and other stakeholders there. We performed standardized, semi-structured interviews with 161 Polish farmers to eva…

LCA applied to an anaerobic digestion plant for biomethane and digestate production

2019

Nowadays it is paramount to promote bioenergy for climate protection, energy security and creation of income/jobs. In this perspective, Anaerobic Digestion (AD) for biogas and digestate production seems to be a viable way to simultaneously improve waste management while producing Renewable Energy Sources (RES). The main objective of this work is to assess the environmental impact associated with biomethane and digestate production from an AD plant as Global Warming Potential, expressed in CO2 equivalents. Therefore, a LCA was carried out for the production of biomethane ready for the injection into the Italian distribution natural gas grid. A mix from different waste sources (cattle manure …

Alternative Ways of Energy Supply in Rural Areas

2019

Optimization of thermal energy and electricity production processes using renewable energy source (RES) is extremely important for agricultural horticultural, and production farms. The article is devoted to the search for the best available techniques to the optimize the process of obtaining heat energy from RES to meet the energy needs in Polish agriculture. The food industry is particularly energy-intensive and as a result, when introducing various innovative technological processes, strong emphasis is placed on rational energy consumption and minimizing its losses, as well as on the secondary use of waste heat. The direct result of using RES devices is also a reduction in greenhouse gas …

Impact of non-programmable renewable sources in Day-Ahead Market in Sicily. Reasons to make more flexible and smarter the national transmission grid.

2014

This article describes technical and market aspects that characterize the Sicilian electrical system, the non-programmable renewable sources impacts on the energy markets (Day-Ahead Market and ancillary services market) and on Sicilian system operation, to evaluate the grid integration of renewable energy sources in a future Sicilian smart grid.

Life Cycle Assessment of Electricity Generation Scenarios in Italy

2018

Hindering global warming and achieving a more competitive, secure and sustainable energy sector are some of the most relevant goals of the 2030 Framework for climate and energy of the European Union. European countries have to identify and implement strategies for contributing to these ambitious goals. In this context, the authors carried out a scenario analysis on the Sicilian electricity mix in order to estimate the life cycle energy and environmental benefits of the increase of the use of renewable energy technologies for electricity production, and the potential contribution of Sicily in the achievement of the European energy and environmental targets. In detail, the authors identified …

Beyond Subsidies: A Study of Sustainable Public Subordinated Debt in Spain

2019

Evidence from business shows that small- and medium-sized enterprises (SMEs) are fragile. They suffer from a high mortality rate that primarily owes to difficulties in securing financing as a result of major information asymmetries. Despite these difficulties, SMEs provide the economic backbone of all economically developed countries. Aware of the key role of SMEs in national economic stability and of the financial problems that SMEs face, governments have designed a range of financial and tax measures to protect them. These financial measures include a highly specific form of public financing called subordinated debt. This concept refers to debt with the lowest credit seniority, just befor…
