I"rate..Other factors that are important are the availability of nutrients and bacteria.

A~'cer the moLTture content of the refuse ha~ <br />reached the level needed for rapid decomposition~ a low perme~bLL[ty materi~J will be placed <br />over the refuse to min/mize additiona/ leachate generation.

The <br /> <br /> of the double liner is approximately $9 million, the cost o! the leachate <br /> system <br /> <br />collec'don system is aproximately $1 mi/lion, and the cost cd the [eachate recycling syst~ iz <br /> <br />approximately $1 million. <br /> <br /> While the accelerated decomposition of shredded municipal refuse and the eventual <br />use of the decomposed refuse as compost is a new concept in this area cd the country, aU ot <br />these unit processes have been demonstrated to be technically possible. Secure landfill~ <br />have been constructed in aU parts cd the country, leachate is being recycled at variotu <br />sanitary land,dj projects in other parts'cd the country, and composting of' municipal refuse <br />has been demonstrated. <br /> <br /> <br />
