Living-Lab-as-a-Service : exploring the market and sustainability offers of living labs in Germany
(2018)
The need of recycling obsolete mobile phones has significantly
increased with the worldwide propagation of mobile phones and
their inherent rapid turnover. In this article, we examine the
acceptance of mobile phone return programs by using the
Technology Acceptance Model and multiple case studies. Our
findings can provide valuable recommendations for the setup of
future mobile phone return programs.
The field of nutrition is facing numerous social, ecological and economic challenges in the coming decades. The food industry belongs to the most significant economic sectors worldwide and the increasing population of 9 billion in 2050 will cause a growing demand on food. So far, changing lifestyles, especially the global rising consumption of meat and dairy products are increasing environmental damage. Moreover our health and wellbeing are the direct result of healthy or unhealthy nourishment and influence follow-up indicators like individual and public health, the expense of the health sector and work productivity.
The material footprint is a tool to measure and optimize the resource consumption of both products and their ingredients and the production processes along the whole value chain. It covers the whole life cycle of the products, from the extraction of raw materials to the processing industry, distribution, consumption, recycling, and disposal. In order to decrease resource consumption to a level in line with the planetary boundaries, the material footprint of household consumption should achieve a level of six to eight tonnes per capita in a year by 2050. This means a reduction in natural resource consumption by a factor of 5 to 10 in Western European countries. In order to ensure a decent lifestyle for all people in 2050, also the material footprint of nutrition has to be reduced significantly by 2050.
The paper shows the relevance and role of nutrition in the overall material footprint of households on the basis of existing studies on the overall resource consumption caused by household consumption. Quantified meal and diet examples are given. It also discusses the causes of food waste and raises the question how a reduction of food waste is possible and can help decreasing the resource consumption in the food sector.
Domestic sustainability innovations are considered to play a key role for pathways to sustainable consumption. The paper shows how open innovation processes can lead to such sustainable innovations, by means of an experimental and interactive infrastructure. It presents how – based on results of the LivingLab project conducted at the Wuppertal Institute within a European Consortium (Lead TU Delft) - currently an extended Sustainable LivingLab approach is developed and applied in two joint research projects at national and international level. To conceptualise this approach, we refer to recent proceedings in innovation and sustainability research, i.e. practice theory to analyse sustainable product design. Focusing on technical solutions and individual behaviour while assuming people's needs as fixed entities, disregards the dynamics of everyday practices in which technologies themselves create needs. Therefore, the consumer's position should be strengthened through userdriven innovation. LivingLabs are combined lab-/household systems, which put the user, i.e. the home occupant, and value chain related actors (producer, handicraft, etc.) on centre stage in the innovation process. We introduce its research agenda and the Three Phases Model of research. We hypothesise that at the end of this userintegrated innovation process developed products have a higher chance of successful diffusion. To illustrate this, we show how the LivingLab infrastructure is employed for the German InnovationCity Ruhr and how it can promote the development of user-centred sustainable consumption strategies.
