garbage collection
<programming> (GC) The process by which dynamically allocated
storage is reclaimed during the execution of a program. The
term usually refers to automatic periodic storage reclamation
by the garbage collector (part of the run-time system), as
opposed to explicit code to free specific blocks of memory.
Automatic garbage collection is usually triggered during
memory allocation when the amount free memory falls below some
threshold or after a certain number of allocations. Normal
execution is suspended and the garbage collector is run.
There are many variations on this basic scheme.
Languages like Lisp represent expressions as graphs built
from cells which contain pointers and data. These languages
use automatic dynamic storage allocation to build
expressions. During the evaluation of an expression it is
necessary to reclaim space which is used by subexpressions but
which is no longer pointed to by anything. This reclaimed
memory is returned to the free memory pool for subsequent
reallocation.
Without garbage collection the program's memory requirements
would increase monotonically throughout execution, possibly
exceeding system limits on virtual memory size.
The three main methods are mark-sweep garbage collection,
reference counting and copying garbage collection.

Waste collection
Waste collection is a part of the process of waste management. It is the transfer of solid waste from the point of use and disposal to the point of treatment or landfill. Waste collection also includes the curbside collection of recyclable materials that technically are not waste, as part of a municipal landfill diversion program.
