An investigation of selected monoaromatic hydrocarbons released from the surface of polystyrene lids used in coffee-to-go cups
PublicationA consumer trend towards the fast preparation of beverages has increased the popularity of hot beverages (especially coffee and tea) available in disposable containers called coffee-to-go cups with fitted polystyrene lids. Lids in contact with hot beverages may release low molecular weight organic compounds into the gaseous phase causing direct exposure of consumers to these compounds during drinking. The paper describes in detail...

Coffee silverskin as a potential bio-based antioxidant for polymer materials: Brief review
PublicationCoffee silverskin is one of the by-products generated by the coffee industry. Although it is not the most burdensome one, because it stands only for ~4.2 wt % of coffee, it seems like an auspicious raw material for industrial processes. Coffee silverskin is characterized by a relatively low moisture content of ~5–7%, so it often does not require quite energy-consuming drying processes. The chemical composition of coffee silverskin,...

Potential applications of by-products from the coffee industry in polymer technology – Current state and perspectives
PublicationCoffee is one of the most popular beverages in the world, and its popularity is continuously growing, which can be expressed by almost doubling production over the last three decades. Cultivation, processing, roasting, and brewing coffee are known for many years. These processes generate significant amounts of by-products since coffee bean stands for around 50% of the coffee cherry. Therefore, considering the current pro-ecological...

Udany projekt instalacji fotowoltaicznej - jak go zrealizować?
PublicationDo tej pory instalacje fotowoltaiczne stanowiły raczej marginalne źródło energii elektrycznej w Polsce, a ich okres zwrotu szacowany był na ponad 20 lat. Wprowadzenie planowanych przez rząd regulacji prawnych i proponowanego systemu wsparcia pozwoli skrócić okres zwrotu inwestycji PV niemal 3-krotnie. Spowoduje to prawdopodobnie powstanie na terenie naszego kraju szeregu realizacji inwestycji fotowoltaicznych, mających na celu...

Where Did Knowledge Management Go?: A Comprehensive Survey
PublicationKnowledge Management (KM) research outputs have been expanding exponentially in the past years, generating diversified topics, which lack integration and classification. It has been challenging for experts to classify KM because of its versatile open fields, and in our view, it contributes to the technocratic approach remaining behind the organizational approach. This paper highlights a way to classify KM publications through a...
