One of the biggest complications in recycling are the mixed materials. Miscellaneous products are hard to recycle because the materials must be separated to effectively process and then reuse them.
When recycling construction and demolition debris, waste screening is an essential practice; it involves taking the waste material and separating it into multiple grades or separating the mixed material by type. This can be done manually, but it takes too long. Alternatively, materials can be hauled to processing centres, but the process is logistically challenging, costly, and has health and safety implications for site contractors and the general public, due to the large vehicles moving in and out of the site.
So, is such an important task really difficult and costly? Not really. In fact, it is pretty simple if you look at it from another perspective - from the operator’s view from the cab. Simply process the mixed material where it is lying by using the heavy equipment with an MB Crusher screening bucket.
Attachments like boom extensions permit the operator to carry out more tasks than just digging. MB’s screening bucket will facilitate and speed the separating of mixed material, consequently reducing landfill waste and saving time, labour and money. The attachments are simple to use and will work with any brand of carriers.
Contained environment and compact recycling centre
J&L Equipos in Colombia demonstrated that not all waste requires removal from the site, as using excavator attachments (even in a small city area) recycling can be done. Cleaning the demolition debris will allow repurposing of the soil and also enable size reduction of the parts inside the rotating screener. Reduction with an MB jaw crusher bucket and the all cleared-out material can be reused.
Norvàn General Contractor in Puerto Rico needed to maximize usage of all the materials. On an island, procurement can be arduous. For them, the use of the screening bucket has sped operations. Scoop. Screen fine on truck bed and unload remaining in another. One man, one machine, and the mixed material is separated, cleaned and ready to be used or reduced by the jaw crusher.
Suitable for all types of carriers
The MB-S18 was mounted on a Hitachi 250 LC a 25-ton machine and the MB-S10 was mounted on a Caterpillar 307E an 8-ton. In Mallorca, the company Trans Pep Soler had a 8-ton Komatsu WB 97 S5 backhoe loader so they bought an MB-LS170. They would take the mixed material to a recycling plant because the sandstones were mixed with cement and demolition debris, which could not be used. After installing the screening bucket, they managed to clean the material by themselves; besides avoiding the cost of the plant they also recovered the sandstone, which is now used for a variety of tasks.
