Some of these aspects are surface material and finish, gasket material and gasket design, welding quality and welding location, cleaning procedure, and internal design of the equipment. This chapter focuses on the relationship between flow of detergent during cleaning and, as a direct consequence, the design of the equipment. At first glance, flow of detergent might not be the most important aspect in cleaning; nevertheless, it is an aspect that is relatively cheap to optimize through design consideration. Additionally, increased focus on environmental concerns (and taxes) related to energy consumption and use of chemicals has made the obvious choice of increasing the temperature or use of harsher chemicals unattractive from an economical point of view—improved cleaning is obtained more cheaply through proper design of closed equipment.

The aim is to increase the flexibility and the variability in the production as well as the focus on freshness and nutritional status of the foods produced. Hence focus is turned to time and work planning in the production, as well as the use of semi prepared elements and the awareness that the production and distribution are means of satisfying the consumer at the time when the food is served. To do this, with out increases in production costs, the production must be highly planned and contain as few steps as possible. This can be optained when basing the planning on the philosophies contained in Lean Thinking.

The results of sustained effort are now starting to show in treatment results as well as in the development of products and the company base. More than 200 biotechnology based drugs have been developed and it is estimated that sales of the nine drugs approved last year will rise to 2.5 billion euros already this year and to 6.5 billion euros in two years' time. In addition to drugs development, biotechnology is utilized e.g. in the development of novel genome research based diagnostics, vaccines, implants, tissue engineering, regenerative medicine, biosensors, which all have notable prospects in the prevention and treatment of diseases and traumas. BioneXt Tampere investment and development programme strengthens biotechnology expertise in the Tampere area. The programme's focal areas are implants and tissue engineering, immunology and bio ICT. Tampere has for a long time been in the global front line in the research of bioabsorbable materials and commercialization of bioabsorbable surgical implants. Emerging in this field are also companies which have set their aims on next-generation products that actively affect the body's healing process. One of the missions in Tampere is to combine expertise in biomaterials, tissue engineering and medicine to develop bioabsorbable implants containing stem cells. This would enable the repair of tissues that do not otherwise heal or where the healing process is extremely slow. Tampere hosts active research and business related to molecular biology, immunology, cancer genetics and vaccines. The institutes in these areas have received several international and national recognitions. Active research has also produced several spin-off companies. Vibrant business and research activities have also given rise to demand for services and companies manufacturing medical research equipment. Resources are therefore also being directed into computer-aided processing of biological information (bio ICT) and services related to the tissue engineering. New industry has already emerged in this field and new companies are emerging all the time. For Finland, it is worth continuing to invest in the development of high technology and biotechnology. Development of recent years in US has shown that there are significant prospects in the field both in terms of economy and science. In consequence of the wideness of the field there is room and profit for those who have the will and the persistence to take things further.
