Reusable items

Place reusable items in a plastic bag or hamper away from your other personal clothes and away from the family laundry. Place disposables in a separate plastic bag or container. The pesticides remaining on your personal protective equipment, work clothing, and other work items could injure persons who touch them. Do not allow children or pets near them. Do not allow contaminated gloves, boots, respirators, or other equipment to be washed in streams, ponds, or other bodies of water.

Broken glassware, which may be contaminated, must be picked up only by using mechanical means such as tongs, brush and dust pan, or forceps—never with bare or gloved hands. Contaminated reusable items, such as sharps, may not be stored or processed in a way that requires employees to reach into containers where the contents cannot be seen or safely handled. 

Dry heat sterilisation is used for equipment that can withstand high temperature and dry heat but cannot withstand wet or steam autoclave. This method is often used for glassware as it dries and sterilises in one operation. The pipets must be wrapped in dustproof aluminum foil or placed in metal pipette cans. The can lids are removed during heating and replaced after sterilisation, that is before any dust can get in the can. Disposable items are not recommended for dry heat sterilisation. This method may only be good for permanent reusable glass pipettes. 

Clean all reusable personal protective equipment items between uses. Even if they were worn for only a brief period of exposure to pesticides during that day, wash them before you wear them again. Pesticide residues that remain on the personal protective equipment are likely to continue to move slowly through the personal protective equipment material, even chemical-resistant material. If you wear the personal protective equipment again, pesticide may already be on the inside next to your skin. Also, personal protective equipment that is worn several times between laundering may build up pesticide residues. The residues can reach a level that can harm you, even if you are handling pesticides that are not highly toxic. 

The first step in achieving longer wear is to replace throwaway items by reusable ones. Even the reusable ones will wear out eventually. If the process is understood, it may be possible to intervene by altering the design or manner of use so that a longer service life is obtained. 

Single-use throwaway items require more energy to make than reusable ones on a per use basis, as discussed in Chap. 14. The production of ammonia for fertilizers is energy-intensive. Much of it could be replaced by leguminous cover crops, less lawn, as mentioned in Chap. 11. Run-off of excess fertilizer has caused a dead zone of 6000... 

In conclusion, even if many efforts must be still devoted to face the four above rcpt>rtcd items, some encouraging results have been obtained such as the possibility to obtain under heterogeneous catalysis comparable activity with respect to the homogenous one and the etllcicni reusability of the supported guanidine. These aspects allow to feel moderately confident about the future of a possible large scale application of this kind of solid catalysts. 

The 3Rs of dealing with waste include reduce, reuse and recycle. The first two items are comparatively highly beneficial to the environment. As defined by the U.S. Environmental Protection Agency (EPA), reuse refers to the following Use a product more than once, either for the same purpose or for a different purpose. Reusing, where possible, is preferable to recycling because the item does not need to be reprocessed before it can be used again (EPA). Reusable means the potential of a product for reuse as defined above and that facilities exist to make such reuse economically feasible (SMART, 2004). 

There is a rival school of thought when it comes to reuse. The first one is that a product can be reused for the same function until its functional life permits and the other option is that after a product s functional life ceases, it can be reused for a different purpose (maybe inferior to the previous one). The first type of reuse includes usage of a product by the same user or the product is donated or sold by the first user to the second one, accomplishing the same function in its second life as in its first life. Reusability of a product is defined as the ability of an item to be used repeatedly, unlike a disposable product. A similar definition can easily be adopted for textile products. 

First fires without metallic fuel are nowadays mainly found in fireworks items. The most important one of this class is black powder. It is fairly safe to handle, often serves as a combined ejection and ignition material, and is itself easily ignited over a wide range of temperatures and at diminished atmospheric pressure down to about 0.1 atm. Its property of fouling metal parts because of the corrosiveness of its reaction products need rarely be considered since pyrotechnic devices are one-shot items and if ejected from reusable dispensers their own expendable case is the actual gun barrel. Black powdo has been discussed in some detail in Chapter 20.

Waste minimization methods used for chemical waste can be used to reduce or eliminate the chemical hazard of chemical-biological waste. Some laboratories that generate biohazardous waste have replaced disposable items with reusable supplies, which are disinfected between uses. 

Lean producers insistence on reusable containers with item-specific dunnage is puzzling to those who are not used to it, because it appears to be an unnecessary expense. Why not just use pallets and disposable cardboard boxes Single-use containers appear to be cheaper, even after including their disposal cost. Let us explore why it is not so.
