Food waste

There are numerous misconceptions about the sources of various chemical elements in waste, particularly those that are potential acid formers when the waste is incinerated or mechanically converted and used as a refuse-derived fuel. For example, it is often mistakenly stated that the source of chlorine in waste, hence a potential source of HCl emissions, is poly(vinyl chloride). The relative contents of selected, potentially acid-forming elements in the organic portion of a sample of waste collected from various households in one U.S. East Coast city is given in Table 2 (17). In this city, a chief source of chlorine in the waste is NaCl, probably from food waste. [Pg.543]

Food wastes. Food wastes are the animal, fruit, or vegetable residues (also called garbage) resulting from the handhug, preparation, cooking, and eating of foods. The most important charac teristic of these wastes is that they are putrescible and will decompose rapidly, especially in warm weather. [Pg.2231]

Rubbish. Rubbish consists of combustible and noncorn-bustible sohd wastes, excluding food wastes or other putrescible materials. Typically, combustible rubbish consists of materials such as paper, cardboard, plastics, textiles, rubber, leather, wood, furniture, and garden trimmings. Noncombustible rubbish consists of items such as glass, crockeiy, tin cans, aluminum cans, ferrous and other nonferrous metals, dirt, and construction wastes. [Pg.2231]

Biofuels rely on organic feedstocks such as plant oil, food wastes and trees but their larger scale and rapid exploitation to meet government targets is stressing large areas of land and associated systems such as water, food production and recreation. A truly sustainable future for biofuels and other eco-system exploitation for industrial value requires a better understanding and more quantitative assessment of a number of critical issues ...

In this chapter we will consider the following as examples of radiation chemical applications (1) dosimetry, (2) industrial synthesis and processing, (3) irradiation of food, waste, and medical equipment, and (4) low-energy ion interaction with matter. Dosimetry is of fundamental importance for yield calculations and also for personnel exposure. Industrial processing would include... [Pg.362]

The composition of industrial wastes varies depending on the industrial structure of a country or region. It consists of general rubbish, packaging, food wastes, acids, alkalis, oils, solvents, resins, paints, mine spoils and sludges. A proportion of the industrial waste is classified as hazardous waste because it contains materials that are presently or potentially hazardous to humans and other living organisms. [Pg.464]

Maintenance and environmental control. While diet, breathing, temperature, and waste removal are virtually taken for granted in most rodent work, they form serious problems with aquatic animals. Knowledge of dietary requirements and prepared diets generally are nonexistent for most species oxygen must be supplied and toxic gases removed temperature maintenance and water composition are very important and the decay of food waste and excreta must be avoided.
