Litter abatement

Figure 12.4 Computer estimates of the effect of various strategies for litter abate-...

The technology and role of photodegradable plastics is considered and computer models are described to evaluate strategies for litter abatement, and experimental studies of the synthesis and biodegradation of conventional and photodegradable polyethylene, polypropylene, poly(ethylene terephthalate), and polystyrene. 

The highest profits for clinoptilolite seem to be achieved in the field of cat litter, animal bedding, and odor absorbents. With increasing environmental conscious applications in pollution abatement gain importance, in particular, if large amounts of ion exchanger or absorber are needed. The versatility of surface modified clinoptilolite is not fully explored yet. As the recent example of sorption [52,53] on the surfactant indicates, many other applications seem possible where the advantages of the porous bulk structure are combined with specific properties of well-chosen surfactants.
