Municipal waste in US has been growing steadily because of the lack of effective implementation of environmental public policy. The laws are breached and this has played a key role in the increase. Other factors include the increasing level of population that has triggered increased production that has resulted to the increased level of the solid waste. Municipal solid waste management has also failed in terms of its programs geared at effective management of the wastes.
- What are some alternatives to municipal solid-waste disposal in landfills?
Some of the alternatives to municipal waste disposal in landfills are recycling part of the waste that is recyclable. This will help to reduce the amount of solid wastes. Another way is to designate specific areas that are not productive for disposal of such solids. This will contribute to efficient utilization of the resources in the municipalities. Other alternative method is combustion in a controlled way to reduce the volume of the waste. Combustion helps to facilitate production of steam and water as a byproduct that can generate energy. Advanced technology can also be adopted through well-managed landfills that can generate methane.

Waste management ensures that there is better disposal of the waste to avoid pollution and other problems. Therefore, selecting the best strategies even if combined to manage waste is something welcome and which should be supported.
