Olojoba (2009), stated that wastes are substance produce in man's day to day activities, through the process of consumption, recreation, production etc. which are unwanted and are no longer useful to originator. ... Methods of solid waste disposal . Solid waste disposal methods according to Aibor and Olorunda (2007) can be grouped under ...
Moreover, illegal disposal of waste tires can collect stagnant rain water pools in their curvy shapes. These conditions enhance the leaching of toxic compounds (e.g. heavy metals) from waste rubber, ... which allows minimalize specific energy consumption of pulverization process. Particle size of GTR obtained by this method was below 200 μm.
Pulverization and Mechanical FDR. For mechanical FDR, apply granular material to the area to be reclaimed ... workmanship and to verify that the construction process meets specification requirements; ... Verify the application rate by evaluating the mass of recycled material against the volume of recycling agent used for a single tanker.

A two-stage process for recycling of vulcanized rubber was proposed. In the first stage, the vulcanized rubber was shredded into granulates, and then the granulates were pulverized into fine ...
Early methods for the disposal of waste rubber products were through land filling or sometimes to be reused as fuel sources. Scrap worn out tires from various automobile industries are the major source of reclamation of waste rubber. 7 Apart from tires, rubbers are utilized in the automobile industry in several other aspects such as in conveyer belts, hoses, …
The primary purpose of asphalt pulverization in roadway rehabilitation projects is to rejuvenate and strengthen damaged pavements while minimizing waste and reducing costs. This environmentally friendly technique maximizes the use of existing resources, shortens construction timelines, and provides a solid foundation for the new road surface.

Nevertheless, the conventional pulverization steps such as mechanical pulverization and ultra-high temperature atomization are energy-intensive . Recently, a process of alloying/dealloying alloy scraps by virtue of the active metal was used to convert bulk alloy scraps to porous and fragile alloys and then to metal powders by mechanical ...
Recycling of waste plastics is of great significance for human society. The pulverization of waste film plastics is a key technical link in the development of collaborative utilization of waste plastics in the steel industry. In this study, waste polyvinyl chloride film plastics were first heated at different temperatures; then the de-chlorination ratio pulverization …
