Free newspapers may offer different news contents to different audiences, when compared with traditional, paid-for newspapers, but they, nevertheless, concentrate on news, and thereby provide society with information on current affairs. These papers have seen circulation rise until 2008; after that, a decline set in, leading to closures and often a monopoly situation in the mature European newspaper markets covered in our research. Free newspapers seem to follow a typical life cycle pattern, moving from growth to maturity, and to saturation and decline. Diversification strategies – home-delivery, weekend, sports, afternoon, and financial – have been disappointing so far. There is no evidence, however, of total extinction, indicating that there is room for at least one title – possibly two – in every market. The situation in the surveyed markets also suggests that a free newspaper may be a ‘natural’ monopoly.

This papers presents some ideas to use so-called software agents as a software representation of a product not only during manufacturing but also during the whole life cycle of the product. Software agents are autonomous entities capable of collecting useful information about products. By their design and capabilities software agents fit well in the concept of ubiquitous computing. We use these agents in our newly developed manufacturing process. This paper discusses further use of agent technology.

The 'AgroCycle' project investigates whether a cooperation of farms can become self-sufficient in energy and fertilization by using manure and organic waste streams for the production of energy, green fuel and green fertilizers by means of anaerobic digestion (AD). In the project, the project partners aim to link the nutrient cycle (from manure to digestate to green fertilizer) to a self-sufficient energy system (biomass to biogas to green fuel for processing the land) through the combined production of biogas and green fertilizers. The financial feasibility of a bio-digester is highly dependent on the use and economic value of the digestate. This combined approach increases both feasibility and sustainability (environmental impacts and CO2 emissions). To explore the feasibility of the aforementioned concept, use is made of the existing 'BioGas simulator' model developed by Hanze UAS to simulate the technical process of decentralized production of biogas and the economic cost.
