Construction and demolition

Dust can be emitted wherever solids are mined (e.g. in quames), processed (e.g. flour mills, woodworking factories, metal smelting and foundries), or handled/transported in particulate form. Construction and demolition operations also generate dust.

HAZARD ASSESSMENT OF MAALAEA CONSTRUCTION AND DEMOLITION LANDFILL SMOLDERING FIRE, AND AIR QUALITY AT A NEARBY COMMUNITY 185... 

A Construction and Demolition landfill near Maalaea Maui caught fire on about 26 January, 1998. Landfill operators retained consultants to assist in putting out the fire. After repeated injections of liquid carbon dioxide and application of a soil cap, the fire was subdued to the point of no visible smoke as of early February 1998. Residents of the Maalaea condominium community condominiums, about one mile due south, had complained of...

Section 2 - Material Hazard Data. This section contains a list of all the materials to be found on the plant - raw materials, intermediates, by-products, effluents, emissions from other facilities close by, catalysts, support materials, services, principle materials of construction and materials encountered during construction and demolition. 

Construction and demolition wastes. C D wastes that come from razed buildings and other structures are classified as demolition wastes. Wastes from the construction, remodeling, and repair of commercial and industrial buildings and other similar structures are classified as construction wastes. These wastes may include dirt, stones, concrete, bricks, plaster, lumber, shingles, and plumbing, heating, and electrical parts. 

The amount of plastic waste generated is still considerably less than that of plastics produced in numerous applications (building, furniture, appliances) plastics meet longterm requirements before their disposal and therefore do not yet occur in the waste stream in big quantities. The majority of plastic wastes are found in municipal solid waste (MSW), as well as in waste streams arising in distribution, agriculture, construction and demolition, furniture and household ware, automotive, electronic and electrical, or medical applications. For a number of years the APME has ordered studies to be made that compile inventories of on the one hand production figures, on the other waste arising, by resin, country, and application and activity. 

About a half (51%) of the recycled wood used was obtained from demolished buildings. Wood resources generated from demolition can be a promising raw material for PB production, because the amount of waste wood in construction and demolition is estimated to be about ten million m3 per year (3). 

There are two types of recycled wood chip obtained from house construction and demolition. These are called P-chip and S-chip (8). P-chip is defined as high quality knife-cut chips obtained from sound timbers or lumbers with a relatively large cross section as used in house construction. P-chips are mainly used in the pulp and paper industry. S-chip is a general term for crushed chips obtained from demolition wood or recycled wood. S-l chip is a high grade chip in for paper or board making. S-2 is for the board industry, and S-3 a low quality chip is for fuel.
