Small-scale disposal

In a review of the comparative properties of sodium and potassium, the latter is rated as invariably the more hazardous [1]. Laboratory procedures for safe handling of potassium have been detailed [2], A safe method for disposal of potassium residues in bulk storage and processing vessels has been developed. Basically the method involves reaction of the metallic residues with dry (condensate-free) steam under closely controlled conditions. It may be used where small-scale techniques... 

Tire pyrolysis operations are currently small scale. Large scale operations would not be economically feasible at present. Economically, pyrolysis is a marginal venture. Unless area tire disposal costs are high, on-site energy savings can be realized, tax advantages are present, and... 

Home is the most important setting for infants and young children. They often eat, play, and sleep in the same area. Examples of sources of exposure to pollutants include building materials (e.g. wood treated with arsenic-based pesticides), lead-based paints, insecticides that are sprayed indoors, fuel (e.g. coal and wood) for indoor cooking, disposal practices for domestic waste (e.g. incineration), household chemicals (e.g. solvents), and small-scale enterprises at the family residence (e.g. brick producers who operate low-technology combustion kilns and makers of pottery using lead-based paints). 

The biological, chemical and physical techniques tend not to have what it takes for complete and ultimate disposal. The potential advantages would include, for example, reduction of the waste volume and/or of the environmental risks. While various research institutions in industrial countries are investigating new methods of disposal, each of them tends to focus on certain specific problems, usually on a small scale. Such methods and technologies are of only limited value for developing countries with real problems, where large quantities of obsolete pesticides and baseline pollution are in need of disposal. Often the waste in question does not consist of a pine substance but of a mixture made iq> of several substances that are no longer individually identifiable. In almost all... 

Fig. 9.3. Small-scale preparative electrophoresis apparatus by Popescu et al. (1971), The glass tube containing the gel (0.8 cm o.d.) fits into the sawn-off barrel of a 2 ml disposable plastic syringe, in which have been cut 2 mm wide slots. A peristaltic pump, working on the outlet tube causes buffer to be drawn through the compartment made up by the syringe bottom.

These variations were caused by the amount of water used for cleaning the fermentation tank, the period of sampling time and so on. In Korea, wastewater treatment utility is mandatory for Makkoli factory that has a capacity higher than 30,000 1/day Makkoli production. Unfortunately, more than 70% of Makkoli was produced by small scale local manufacturers and the wastewater is disposed to the drain, causing a serious contamination to sewage. 

Consistency of product quality is demonstrated by showing operating consistency and product quality from batch-to-batch, processing with only buffer (blank runs) with assays for contaminants, examination of cleaned surfaces and materials, and extended scale-down clearance studies on reused materials. Disposable processing components that eliminate the need for cleaning validation are increasingly used at small scale. 

It is recommended that unauthorized manufacture should not be a criminal offense unless it is done with purpose to sell or otherwise dispose of a controlled drug. Illicit manufacturers usually manufacture depressant or stimulant drugs to distribute them. However, some controlled drugs may be made on a small scale for personal use. Thus, it... 

On a small scale, laboratory quantities of the BTF s can be safely combined with other halogenated compounds for appropriate disposal [29].
