Things that help speed up the composting process are: shredding the materials (smaller particle size), mixing nitrogen (green stuff) and carbon (brown stuff) material about half and half, keeping the pile moist (decomposing microbes need moisture), but not too wet (anaerobic decomposition produces foul odors), and finally turning the pile periodically to mix outer material into the center of the pile. Additionally, make the pile large enough to heat up well (4 feet in diameter is about right), and don’t include dairy products, grease or meat as these tend to attract unwanted visitors to the pile.
