Garden wastes

Many materials, such as kitchen and garden waste and animal manures, are composted before use to stabilize the plant foods they contain, and to make them easier to apply. 

The composting miracle If you get the mix of ingredients right, then time, and the activity of helpful organisms, is all you need to transform your kitchen and garden waste (below left) into finished oompost (belowright) a rich, crumbly soil-like material with a pleasant earthy smell. 

Superior lifecycle eco-efficiency (e.g., for garden waste bags)... 

These included exposure to sterile water or air at 60 °C, pure fungal cultures and garden waste compost. This study showed that during a period of 50 days, water and air had very little or no effect on the degradation of PHVB in garden waste compost. The degradation was due to microbial action only. 

LATS is a market-based mechanism that introduces progressively tighter restrictions on the amount of paper, food and garden waste that authorities can landfill. Local authorities are allocated an annual landfill allowance for municipal biodegradable waste. They are under a duty not to exceed this allowance and face punitive fines for every tonne landfilled above the total amount of allowances they hold. EU fines imposed on the UK for failure to meet the targets will be split between local authorities in direct proportion to their contribution in breaching the targets. 

In the field of waste management, natura supplies biodegradable waste bags in many different shapes and sizes, from 8 to 240 litres. The bags are used for kitchen and garden waste bins and compost easily after use. 

Collect materials. Good raw materials for compost include garden wastes, grass clippings, kitchen scraps, manure, newspapers, and sawdust. Avoid meat scraps and oils, both of which will attract forasins animals and will... 

Two products are usually obtained by density separation (1) the light fraction, which is mainly composed of organic materials (paper, plastics, food residue, garden waste, etc.) and (2) the heavy fraction, composed of inorganic materials (metals, construction debris, heavy plastics, etc.).

Compost If you have an outdoor space, compost your kitchen and garden waste. 

The typical composition of municipal solid waste (MSW) from the UK, an Asian city and a Middle East city is shown in Table 7, and shows that for the UK, a large proportion of the waste is biodegradable. Assuming that the unsorted fines are biodegradable, then the total proportion of waste that is biodegradable is equivalent to 65.8% (this includes paper, putrescibles, unsorted fines, garden waste, textiles and wood). 

In the past, lawn and garden trimmings have made up approximately 12% of the waste in municipal landfills. Much lower amounts can be expected from most Army installations. Also, many installations and municipalities are no longer disposing of yard or garden wastes in sanitary landfills instead the waste is land farmed or disposed in non-sanitary landfills, such as approved fill areas. To further reduce the waste streams, many installations now bum wood, recycle metal and other materials, and use dirt, concrete, and brick for erosion control projects. The make-up of landfills vary, but if an installation limits solid wastes to what would normally be placed in a municipal landfill, the composition should compare with table 1-1.
