1. quantity,types of domestic solid waste ecological problems caused by solid waste

Municipal services
The urban centers also contribute immensely to the solid waste crisis in most countries today. Some of the solid waste brought about by the municipal services include, street cleaning, wastes from parks and beaches, wastewater treatment plants, landscaping wastes and wastes from recreational areas including sludge.
Treatment Plants and Sites
Heavy and light manufacturing plants also produce solid waste. They include refineries, power plants, processing plants, mineral extraction plants and chemicals plants. Among the wastes produced by these plants include, industrial process wastes, unwanted specification products, plastics, metal parts just to mention but a few.
Agriculture
Crop farms, orchards, dairies, vineyards and feedlots are also sources of solid wastes. Among the wastes they produce include agricultural wastes, spoiled food, pesticide containers and other hazardous materials.
Biomedical
This refers to hospitals and biomedical equipment and chemical manufacturing firms. In hospitals there are different types of solid wastes produced. Some of these solid wastes include syringes, bandages, used gloves, drugs, paper, plastics, food wastes and chemicals. All these require proper disposal or else they will cause a huge problem to the environment and the people in these facilities.

2.construction and demolition areas
Construction and demolition waste (CDW) accounts for more than a third of all waste generated in the EU. It contains a wide variety of materials such as concrete, bricks, wood, glass, metals and plastic. It includes all the waste produced by the construction and demolition of buildings and infrastructure, as well as road planning and maintenance. Some components of CDW have a high resource value, while others may have a lower value, but could still be easily reprocessed into new products or materials. Technology for the separation and the recovery of construction and demolition waste is well established, readily accessible and generally inexpensive.
When it is not separated at source, construction and demolition waste can also contain small amounts of hazardous materials such as solvents and asbestos. These can pose particular risks to the environment and impede recycling.

Despite its potential, the level of recycling and material recovery of construction and demolition waste varies greatly across the EU, ranging from less than 10% to over 90%. EU counties apply different definitions of construction and demolition waste, which makes cross-country comparisons difficult.
3.methods of solid waste management
There are different methods of solid waste management. The following are some of the recognized methods:
