Supply chain conventional

Irrespective of the fuel supply chain, alternative fuels have generally lower tailpipe emissions in terms of local pollutants (such as NO, CO, S02, VOC and particle emissions) than conventional gasoline and diesel engines for instance, natural gas completely eliminates particle emissions synfuels are manufactured with very low sulphur and aromatic contents alcohol-based fuels have high octane numbers, which...

The total control of the whole supply chain, from discovery research and raw-material sourcing all the way to postlaunch monitoring of patients, has been a key element of the conventional business model for the pharmaceutical industry, particularly big pharma. In view of the challenges facing the industry, the question arises as to whether this business model is sustainable in the long run. 

However, although these aspects are discussed as separate topics below, in line with the way scientific studies and regulatory issues are normally defined, most consumers still see them as parts of a holistic picture where the good intentions of the people involved in the food supply chain are the most important assurance for all aspects of food quality. In this context, stringent safety measures and sophisticated process control, which are the cornerstone of food quality assurance schemes in conventional supply chains, maybe seen by consumers at best as self-imposed restrictions that prove the sincerity of these good intentions, and at worst as unfair, unnecessary burdens introduced through lobbying from big profit business to support its suppression of small-scale or local producers. 

Scenario III Ecologization of conventional agriculture Organic production remains a niche activity, whilst mass volumes of production gradually become more ecological through environmental regulation. This scenario is in operation in Switzerland and Austria and is favoured by many actors in the supply chain. 

The starting point in the textile supply chain is the raw material preparation. Textile fibres are obtained from two main sources natural (cellulose or animal) fibres or synthetic fibres. Natural cellulosic fibres include conventional and organic cottons, rayon, linen, hemp, jute, ramie and sisal. Cotton is used to produce 40% of world textile products (Saicheua et al., 2012). The major environmental concern in cellulosic fibre production, especially for cotton fibre, is the chemical fertilizers and pesticides used during cultivation. The second concern is the high level of water consumption (Dave and Aspegren, 2010 Muthu, 2014). Cotton is one of the most popular natural fibres used in the world. Three percent of the world s cultivated land is used for cotton production and 16% of the world s insecticides are used on this crop alone (Saicheua et al., 2012 Muthu, 2014). Moreover, the use of chemical fertilizers, pesticides, machinery and electricity causes some human health and environmental problems. Also cotton growing requires 7—29 tonnes of water per kg of raw cotton fibres (KaUiala and Nousiainen, 1999). Other types of cellulosic fibres are hemp and flax, which can be considered to be the most significant sustainable fibres in the non cotton natural fibre sector (Werf, 2004 Muthu, 2014). 

Mass customization changes the design and production from made-to-stock to made-to-order. It challenges the conventional product development approaches and supply chain management, from mass production to high-variety-low-volume production. In order to support the paradigm shift derived by the customization process, the enterprise should...
