Auto-thermal, thermophilic digestion process for degradation of a mass of typical municipal solid waste comprises:    (a) mixing waste (WS) with manure (MN) and secondary sewage sludge (SS) to form a compost biomass pile, MN and SS having sufficient moisture and indigenous bacteria (IB) including anaerobic bacteria (AB) to carry out composting of the pile;    (b) allowing the pile to autothermally react until the temp. reaches 115-140 F;    (c) adding an alkaline material throughout the pile to raise pH to 10 quickly;    (d) allowing the pile to autothermally react to a temp. 180 F;    (e) adding nutrients comprising inorganic N, P, S and K to support continuing metabolic reactions within the pile;    (f) allowing the pile to autothermally react while adding water to maintain a moisture level of 60-82% until the biomass degrades to produce a non-pathogenic compost, without mechanical aeration or addn. of gaseous O2.    Also claimed are:    (1) an in situ process for bio-re-mediating a medium contg. HC contaminants comprising:    (i) exposing HC to the above VC;    (ii) assuring the presence of sufficient nutrients and water;    (iii) enzymatically catalysing hydrolysis;    (iv) periodically extracting water contg. bioremediation prods. (BP);    (v) adding fresh water equal to the amt. removed in (IV), and    (vi) repeating steps (iv) and (v) until the site is sufficiently bio-re-mediated;    (2) an ex-situ process for bioremediating a material contaminated with organic or HC contaminants within a container with a granular material (GM) comprising:    (i') mixing contaminated material (CM) with GM,    (ii') submerging the mixt. in the container in water,    (iii') adding the above VC,    (iv') adding nutrients as above and    (v') carrying out steps (iv)-(vi) as above;    (3) a fatty or aminoacid prod. resulting from (1) and (2), and    (4) a process for bioremediating an aq. medium contg. paraffin crude oil (PC) contaminants comprising:    (a) preparing a mixt. of SS contg. 3-5 wt.% moisture and horse manure, SS acting as a wetting agent to form a pile,    (b) adding paper prod. refuse to an aq. medium to absorb the medium thus forming an oily trash mixt.,    (c) mixing the prods. from steps (a) and (b) to form a jelly mixt. contg. 60-70% moisture and    (d) autothermally reacting by enzymatically catalysed microbial action to a temp. of 160 F,    (e) turning after 10 days to expose interior portions of the pile to the exterior,    (f) allowing the mixt. to autothermally react for 30 days and    (g) repeating steps (e), (h) and (f) for 30-60 days until a compost prod. is attained.    USE -   The process is used to biodegrade waste prods. and produce by prods. which are useful for agricultural fertilisers. The early steps stress bacteria to enable them to induce enzymatically catalysed hydrolysed of waste prods. or organics or hydrocarbons in the presence of water.    ADVANTAGE -   Composted prods. are unique and are suitable for use in subsequent processes for bioremediating organic and hydrocarbon contaminant materials e.g. bioremediation of soils or clay.
