Solution: b.

The correct way to manage fresh waste is to expose as much of it to air as soon as possible. Worldwide, the standard way of doing this is to unload the waste in windrows, not high heaps.

• Windrows are long low parallel heaps of waste, not more than two metres high, which are designed to achieve the best conditions for aerating the waste. Only parking-lot type management is required to guide incoming vehicles on where and how to unload their waste, moving slowly forward and leaving the waste behind in a long row. Enough space is left between rows for a lifting tractor or earthmover to drive through and turn the waste in the windrow.
• The outer aerated waste should form the inner core of a new windrow, and the airless centre of the old heap now on the outside. Weekly turning of the waste, repeated at least four times, ensures that all parts of the waste are fully decomposed, like leaves on a forest floor, turning dark brown and with a sweet earthy smell. The process can be speeded up by the addition of composting bio-cultures (fresh cow dung or substitutes available in the market).
• Fresh waste windrows heat up inside, to about 55°C to 60°C in three to four days. After four turnings, there is about 40 per cent weight loss as moisture content declines and also about 40 per cent volume reduction. After this, no leachate or methane or smelly gases are released, and this fully stabilised waste is called compost, rich in microbes as well as humus, both wonderful for soil vitality.
