Two decades of discussion on charitable food aid in Finland : analysing the framing by and through the media

2016

Jo kaksi vuosikymmentä virallisen sosiaalipolitiikan rajapinnoilla toiminut ruoka-apu on murrosvaiheessa: Tulisiko toiminta hiljaisen hyväksynnän sijaan tunnustaa, jolloin avun kohdentamista ja järjestämistä voidaan avoimesti kehittää yhdessä kirkon, kunnallisen sosiaalitoimen ja yksityisen sektorin kesken? Onko toiminnan fokus siirtymässä väliaikaiseksi tarkoitetusta akuutin nälän torjunnasta kohti sosiaalipoliittisen ruoka- köyhyyden ja ekologisen ruokahävikin ongelmat yhdistävää ratkaisumallia? Julkisen, yksityisen ja kolmannen sektorin yhteistyönä toteutettavan saksalaisen ruoka-apumallin (Berliner Tafel -ruokapankkiverkosto) rantautuminen Suomeen (Yhteinen Pöytä …

From Scarcity to Abundance : Food Waste Themes and Virtues in Agrarian and Mature Consumer Society

2019

Uusitalo and Takala address the food waste problem as a societal phenomenon and examine ethical virtues, values linked to them and food practices in two different time periods: agrarian society (1885–1917) and mature consumer society (2008–2017), in Finland. They use data from newspapers to uncover how ethical principles can underpin understanding of the food waste phenomenon. The study shows how the virtues adopted by food chain actors guide their practices towards sustainable ways of handling excess food. While societal themes of food waste are changing, virtues and food practices are changing as well, but some deep-rooted societal virtues and values persist. The chapter concludes with re…

Exploring positive online customer experience formation : a study of food waste shoppers

2022

This qualitative study investigates the formation of positive online customer experiences in the context of online grocery shopping. This study analyzes customers’ written descriptions of the causes of their positive experiences when visiting an online store. Data were collected with an online survey of 581 respondents. The case company is a Finnish online retailer, Fiksuruoka Ltd. Fiksuruoka’s business idea is to sell food waste; its product range consists of surplus groceries that are in danger of being disposed of. The findings show that four main themes contribute positively to the online customer experience. Positive customer experiences were explained by factors related to 1) the shop…

Sustainable Recycling of Insoluble Rust Waste for the Synthesis of Iron-Containing Perovskite-Type Catalysts

2019

Insoluble rust waste from the scraping of rusted iron-containing materials represents a cheap, eco-friendly, and available source of iron. LaFeO3 perovskite-type powders were successfully prepared by solution combustion synthesis using rust waste from an electricity transmission tower manufacturer. Solution combustion synthesis enabled introduction of this insoluble iron precursor directly into the final product, bypassing complex extraction procedures. Catalytic activity in the propylene oxidation of the waste-derived LaFeO3 with stoichiometric Fe/La ratio was almost identical to the commercial iron nitrate-derived LaFeO3 , thus demonstrating the viability of this recycling solution. The a…

Polyphenols and Pharmacological Screening of a Monarda fistulosa L. dry Extract Based on a Hydrodistilled Residue By-Product

2021

This study aimed to determine the composition and content of polyphenols in the dry extract obtained from the hydrodistilled residue by-product of the wild bergamot (Monarda fistulosa L., Lamiaceae Martinov family) herb (MFDE) and to evaluate its safety and pharmacological properties. The total phenolic content (TPC) in the MFDE was 120.64 mg GAE/g. The high-performance liquid chromatography (HPLC) analysis showed the presence of a plethora of phenolic compounds, including hydroxycinnamic acids and flavone derivatives in the MFDE, with rosmarinic acid and luteolin-7-O-glucoside being the main components. With an IC50 value of 0.285 mg/mL, it was found to be a strong DPPH radical scavenger. …

The Influence of Industrial Waste on the Magnetic Properties of Salt-Affected Soils from Two Soda Ash Manufacturing Sites

2021

The aim of this study was to characterize the impact of soda ash manufacturing on the magnetic properties of soils located in the agricultural landscape in north-central Poland. Two study sites were chosen: Mątwy (SM) and Janikowo (SJ). Highly saline soils with halophyte communities were selected in order to develop an understanding of the relationship between salinization of water–soil interface and the potential contamination risk of the environment. Basic chemical and physicochemical properties of topsoil (0–25 cm) and water (surface and groundwater) samples from five locations were characterized. The characteristics of soil contamination were based on the content of sel…

Spatial Succession for Degradation of Solid Multicomponent Food Waste and Purification of Toxic Leachate with the Obtaining of Biohydrogen and Biomet…

2022

A huge amount of organic waste is generated annually around the globe. The main sources of solid and liquid organic waste are municipalities and canning and food industries. Most of it is disposed of in an environmentally unfriendly way since none of the modern recycling technologies can cope with such immense volumes of waste. Microbiological and biotechnological approaches are extremely promising for solving this environmental problem. Moreover, organic waste can serve as the substrate to obtain alternative energy, such as biohydrogen (H2) and biomethane (CH4). This work aimed to design and test new technology for the degradation of food waste, coupled with biohydrogen and biomethane prod…

CIRCULAR PROCESSES FOR A NEW URBAN METABOLYSM: THE ROLE OF MUNICIPAL SOLID WASTE IN THE SUSTAINABLE REQUALIFICATION

2014

Through this paper we present the first results of a research combining the management problem of Municipal Solid Waste to the requalification of built environment. The goal of this research is to mitigate the vulnerability of territory and urban heritage and to transform a problem into opportunities. Above all, we have paid attention to several exemplifying cases of Italian territory: suburbs of large towns, historical centres, small centres (and, in particular, those with a strong historical connotation). Their features are, at the same time, restrictions and challenges for designing new compatible systems that can contribute to the requalification of urban landscape recovering spaces wit…
