Process home factories

In 2008, the global food preservation industry s value exceeded 500 billion. The food preservation market consists of manufacturers that produce technology to perform food preservation processes in factories, businesses, and homes and that develop and... 

Wastewater treatment is an extremely important service-related industry that is carefully integrated into our society. Sewage is defined as water that contains one-tenth of 1% (0.1%) solid waste matter produced by human beings. Sewage is frequently referred to as wastewater. Waste-water comes from sinks and toilets of homes, factories, offices, and restaurants. Sewage contains harmful chemicals and disease-producing bacteria. Without processing, this harmful material... 

One of the most cotrunon processing methods for plastics is injection moulding. Nowadays every home, every vehicle, every office, every factory contains a multitude of different types of articles which have been injection moulded. These include such things as electric drill casings, yoghurt cartons, television... 

The first chapter in this section provides a unique account of the ecology, i.e. distribution, survival and life-style, of microorganisms in the factory environment, and should enable process designers, controllers and quality control personnel to comprehend, trace and eradicate the sources of failure due to extraneous microbial contaminants in the finished product. Much of the information given here is applicable to hospital manufacture also, and this is extended in a contribution (Chapter 19) dealing with contamination in hospital pharmaceutical products and in the home. 

Other suggestions on distributed processing reach beyond the capabilities of today s micro reactors, and hence are of more visionary character [5]. These include desktop pharmacies, home-recycle factories, mobile factories, house-water treatment plants, processing cereal crops at the combine, purification of blood in the body, recycling of plastics in the collection vehicle and more [5]. 

Silver is usually found in extremely low concentrations in natural waters because of its low crustal abundance and low mobility in water (USEPA 1980). One of the highest silver concentrations recorded in freshwater (38 pg/L) occurred in the Colorado River at Loma, Colorado, downstream of an abandoned gold-copper-silver mine, an oil shale extraction plant, a gasoline and coke refinery, and a uranium processing facility (USEPA 1980). The maximum recorded value of silver in tapwater in the United States was 26 pg/L — significantly higher than finished water from the treatment plant (maximum of 5.0 pg/L) — because of the use of tin-silver solders for joining copper pipes in the home, office, or factory (USEPA 1980). 

As we search for the energy sources of the future, we need to consider economic, climatic, and supply factors. There are several potential energy sources the sun (solar), nuclear processes (fission and fusion), biomass (plants), and synthetic fuels. Direct use of the sun s radiant energy to heat our homes and run our factories and transportation systems seems a sensible longterm goal. But what do we do now Conservation of fossil fuels is one obvious step, but substitutes for fossil fuels must be found eventually. We will discuss some alternative sources of energy here. Nuclear power will be considered in Chapter 21. 

Humanity s major sources of energy are derived from fossil fuels, principally oil, gas, coal, and wood. The major combustion by-products of fossil fuel burning include sulfur dioxide (SO2), carbon dioxide (CO2), and nitric oxide (NO2), and partially oxidized hydrocarbons. The process of burning fossil fuels in thermal power plants, factories, homes, and motor vehicles emits enormous amounts of the aforementioned pollutants. The most important environmental concerns resulting from fossil fuel use are global climate change, acid rain, surface ozone, and partic-ulate-Zaerosol-bound toxins. 

The manufacture of a product by a particular route may involve the transport of hazardous materials on a regular basis to the site of manufacture or even between sites. This could pose a very significant risk to the public at large. The quantity of material, the frequency and mode of transport, as well as the safety health and environment (SHE) issues will make or break the process. It is worth bearing in mind even at an early stage of the process that a development decision has to be made to avoid such a process. Other considerations to be home in mind are Can the material be made near the factory site, thereby avoiding its transportation Can the process be changed so that the use of such a chemical could be totally avoided ...
