Closed System
Is a system closed with respect to matter, but energy may be transferred between the system and its surroundings. Earth is essentially a closed system.

Closed System
an isolated system having no interaction with an environment. (Von Bertalanffy, p.3)
a system whose BEHAVlor is entirely explainable from within, a system without input. Systems may be variously closed to matter/ENERGY, to information, and/or to organization . Systems closed to energy are autark, systems closed to information are independent , and systems closed to organization are autonomous (see autonomy ). Biological organisms are largely closed to organization, the latter being specified by the dna at the point of inception. The output has nothing to do with whether a system is closed. Systems without output are non-knowable through observation from the outside (see open system ). (Krippendorff )

The system of operating a paper or board making machine whereby the water drained from the sheet during formation is collected and returned for re-use Instead of being discharged to waste.

Closed system
A closed system is a system in the state of being isolated from the environment. It is often used to refer to a theoretical scenario where perfect closure is an assumption, however in practice no system can be completely closed; there are only varying degrees of closure.
In physics, a closed system can exchange heat and work, but not matter, with its surroundings. In contrast an isolated system can exchange neither heat nor matter with the surroundings. For a simple system, with only one type of particle (atom or molecule), this amounts to a constant number of particles. However, for systems which are undergoing a chemical reaction, there may be all sorts of molecules being generated and destroyed by the reaction process. In this case, the fact that the system is closed is expressed by saying that the total number of each elemental atom is conserved, no matter what kind of molecule it may be a part of. Mathematically:
