Plastics disposal

Application of plastic films for soil solarization requires specific equipments and time-spending procedures, as well as the plastic disposal at crop end can be expensive and represent a serious environmental problem (Parish et al. 2000).

The submitter used a balloon attached by 1" of rubber pressure tubing to the barrel of a plastic disposable syringe bearing a 2"-needle through the septum. 

Important Use phosphate-free test tubes (cleaned with hot diluted HCl) or plastic disposables. 

If the electrode response is sluggish, first check/replace the membrane since most 02 electrode problems are due to dirty or leaky membranes. Remove the cell plug and rinse the cell thoroughly with distilled water using a plastic disposable pipet to avoid the risk of damage to the membrane.

In a few cases, analyses may be done on the process floor using a conventional scanning spectrophotometer and the usual laboratory cuvette or a specially made vial that fits into the sample cavity of the instrument. Cuvettes may be made from quartz (various grades depending upon UV transmission requirements), or from plastic (disposable) when UV wavelengths are not required for the measurements. In most cases these at-line analyzers have lower performance characteristics than dedicated laboratory instruments, but may be quite adequate for the task at hand. However, their use still requires manual sampling... 

The most immediate advantage of making biodegradable plastics is to address the problems of litter and marine pollution resulting from plastics disposal, which are difficult to solve any other way. 

Industrial releases are only a fraction of the total environmental releases of DEHP. Release of DEHP into the environment is thought to originate from diffuse sources, mainly from end-uses of DEHP (e.g., as an additive to plastics). Disposal of plastic products containing DEHP (see Section 5.3) is also a possible source of environmental release (Bauer and Herrmann 1997 EPA 1981). Quantitative information on releases of DEHP to specific environmental media are discussed below. 

Gentry dislodge the cells by a cell scraper, and disperse by gently pipeting up and down several times with a 5-mL plastic disposable pipet. 

Add equal volumes of 1.2% agar at 55°C and 2X alpha medium at 37°C and allow to equilibrate to 37°C for at least 10 min. Use plastic disposable pipets for all manipulations involving agar (see Note 2).

The research and development carried out so far in has shown that, even though microwave pyrolysis will not be the solution to the whole problem of plastic disposal, it certainly has the potential to help reducing the number of resources currently committed to landfill. Evidence of this potential is the number of companies interested in the development of the process and that are currently active, trying to commercialize proprietary microwave pyrolysis processes. However, this chapter has shown that in order to accomplish a more widespread utilization of this kind of processes a better communication between the commercial and scientific communities is needed. The companies with their patents would be able provide many innovative ideas that may help to increase processes efficiency and the scientific community would provide explanations for the improvements, that would in turn generate even more ideas in a self-sustaining cycle of improvement.

Kova slides are plastic disposable counting slides useful for counting cells in Category 3 laboratories where use of glass is inadvisable. Kova slides are available from Bio-Stat Diagnostics (Stockport, UK) or Hycor Biomedical Inc. (California). 

In 1976 plastic became the most widely used material in the United States. It represents a 140-billion-per-year industry8, greater than steel and aluminum combined. Unfortunately the increase in the use of plastic has affected the problem of waste plastic disposal at about the same rate. The need to recycle plastics to reduce the use of virgin resins and to reduce the amount of waste materials has become a subject of considerable interest. 

Butane (C4H10) is the fuel commonly found in plastic, disposable lighters. Butane is a covalent compound, but the molecules have no electrical charge, so the attraction between them is weak. In fact, if the butane were not held under pressure in the lighter, it would immediately boil away to a gas.
