can be used, first of all, as the means stimulating restoration soil properties and in
the second—as organic fertilizer.
Many pathogenic microorganisms do not maintain a competition to other mi-
croorganisms collecting during composting. Besides warmly, allocated at reception
compost, promotes final destruction pathogens. Inorganic waste, glass for exam-
ple, metals and plastic, separate more often before biochemical processing organic
waste, and then if necessary recycle (Weber et al.
2007
; Bustamante et al.
2008
;
Kuba et al.
2008
; Hort et al.
2009
; Ben et al.
2010
). It is known also, that now there
are the special enterprises which are engaged both composting, and release of the
equipment necessary for these purposes. Such manufactures as has shown an ex-
pert, are profitable enough, as compost, received at these enterprises as already it
was marked earlier, is widely used at reclamation arable lands in rural, garden and
park facilities (Neklyudov and Ivankin
2003
).
Process of composting is known since deep times. Still ancient Egyptians have
found out that agricultural crops considerably increased after animal manures in
fields. They revealed that fresh manure renders essentially smaller influence on
ground, and even can sometimes harm in comparison with the manure preliminary
mixed with silt or the vegetative rests. In many cases the increase in efficiency of
such mix needed long enough time, its maturing sometimes reached year and more
(Lima et al.
2004
; Zmora-Nahum et al.
2005
; Smith
2009
; Raj and Antil
2011
; Gab-
hane et al.

). In the further it has appeared, that at correctly picked up parity of
components reception of fertilizers for ground can be carried out for shorter terms
(Neklyudov and Ivankin
2006
).
However only after opening the fact of existence of microorganisms and cre-
ations of new scientific discipline—of microbiology became clear features of re-
ception of similar fertilizers. It has appeared, that efficiency of a method is defined
by participation of various microorganisms and entirely depends on their activity
(Marr and Facey
1995
; Neklyudov and Ivankin
2006
). Process proceeded essen-
tially more quickly increase in aeration of processed components and consequently
it began to name aerobic decomposition of organic substances, or composting (Marr
and Facey
1995
; Smith
2009
). With growth of animal industries, increase in an
intensification of agricultural crops, development of cities and occurrence of the
increasing quantity of waste composting became one of effective means of their
processing and improvement of structure not only the ground, but also a condition
of an environment (Miller
1996
; Tognetti et al.
2011
).
The purpose of the review—consideration of publications for last years, the or-
ganic waste devoted to aerobic decomposition for reception of composts, the analy-
sis of methods of reception and properties received compost.

Raw-material Base of Compost Reception
As raw material for reception of composts any waste containing organic substances
can practically serve: manure of agricultural animals and birds, dirtiness, silt, firm
and liquid organic waste from sewage, city waste, a grass, leaves, hay, straw, waste
