Summary: The National Solid Waste Policy (PNRS) highlights the importance of recyclable materials organizations (OCMR) urban solid waste recycling chain. However, OCMRs have dysfunctions that
impact their productivity and consequently greater gains for
associates, such as non-value-added activities, called waste. One way to understand why these unproductivities occur and how to eliminate them is the basis of Lean Thinking. Thus, this work aimed
to implement improvements in an OCMR based on a wide analysis of evaluated possibilities and the use of Lean techniques such as SIPOC,
process modeling, value stream mapping, spaghetti diagram, analysis of activities that add value and rearrangement of layout. After improvements implemented in the waste selection macroprocess, gains were obtained with reduction of initial stock (59%), lead time (41%), processing time (57%) and cargo handling (17%), clearly realizing the production of positive results in the studied organization. This work revealed the possibility of applying the lean thinking strategy in simple enterprises such as the OCMR, providing increased productivity and revenue, as well as allowing the expansion of municipal selective collection.
