The Waste Management System

Laboratory glassware containing reaction mixtures of unknown nature (and sometimes of unknown origin) can pose difficult disposal problems. Such materials occur frequently in research laboratories, particularly in those that have a high rate of personnel turnover. Simple laboratory tests may provide enough information for safe disposal. The waste management system should provide a procedure designed to prevent the occurrence of such orphan wastes. 

Laboratories should require that any reaction mixture stored in glassware be labeled with its chemical composition, its date of preparation or formation, the name of the laboratory worker responsible, and a notebook reference. This procedure can provide the information necessary to guide disposal of the mixture if the responsible laboratory worker is no longer available. It should be recognized, however, that such a procedure must be enforced. It cannot guarantee that a departing worker will not leave behind unlabeled mixtures. 

The waste management system for any laboratory should be tailored to the

CERCLA has a response focus. Whenever there has been a breakdown in the waste management system (e.g., a release or a potential threat of a release of a hazardous substance, pollutant, or contaminant), CERCLA authorizes cleanup actions. 

The entire system is based on a tiered approach where three layers of technology are integrated into the overall treatment system, as illustrated in Chart 2. First, a distributed process control system is network linked to the various component subunits of the waste management system such as pH control, ion-exchange control, tank level control, etc. Next, are the recovery/treatment processes themselves. The final tier is a monitoring system which controls both the performance of the treatment systems and the discharge assurance of the plant effluent...

In fact, effective industrial pollution prevention is definitely better than its cure. The first objective must be reduction in the amount of waste produced, if it cannot be avoided. The second objective is to manage the waste in a suitable way while minimizing the overall burden associated with the waste management system [8]. 

The third level is treatment. Generally, treatment of a waste renders it less hazardous or nonhazardous but does not allow reuse of the material. For materials that have no potential for recovery and are not amenable to source reduction, treatment—such as neutralization of acids, incineration of organic sludges, and oxidation of cyanides— becomes an important part of the waste management system. 

Also, and particularly because of the widespread perception of the hazards associated with radioactivity, it is essential to view the waste management system in both space and time. As with many industrial activities, the wastes arising from activities which involve radioactivity may have an impact beyond the borders of the country of origin. This has to be managed in a responsible and fair way and in a way that is accepted as being so by the international community. Equally, the wastes may have impacts, direct or indirect, over lengthy periods of time and it is a matter of basic ethics to ensure that the consequences of present day activities, from which the benefits have been essentially contemporary, do not fall unnecessarily on future generations nor in any way that would be unacceptable to contemporary society. 

These requirements for human health and safety are common to all forms of radioactive waste and to each step of the waste management system. What follows, therefore, are those other safety requirements specific to each step.

In general, the controls and instrumentation of the waste management systems are not required to be redundant. However, if the controls and instrumentation are for systems important to safety, redundancy should be provided. If the control function that would initiate a shutdown is not redundant, it shall be designed for an automatic fail-safe followed by a shutdown. 

In some cases, the waste management systems and opterational radiological safety are discussed separately. 

Biopolymers generally have lower heating values than most petrochemical bulk polymers (Table 7). In some cases the difference is negligible (e.g., PH3HB versus PET), while in other cases it is substantial (starch polymers versus PE). In practice, the difference in recoverable heat may be even larger than indicated by Table 7 due to the feature of most biopolymers to absorb water rather easily. The choice of the waste management system may therefore have a considerable impact on the... 

Often, information is difficult to track during a disaster response, particularly when there are many different organizations involved in the waste management system. Despite this, an effort, be it paper based or electronic, should be made to monitor waste movement from source to disposal.
