Sawdust Burner
A wood waste burner, known as a teepee burner or wigwam burner in the United States and a beehive burner in Canada, is a free-standing conical steel structure usually ranging from 30 to 60 feet in height. They are named for their resemblance to beehives, teepees or wigwams. A sawdust burner is cylindrical. They have an opening at the top that is covered with a steel grill or mesh to keep sparks and glowing embers from escaping. Sawdust and wood scraps are delivered to an opening near the top of the cone by means of a conveyor belt or Archimedes' screw, where they fall onto the fire near the center of the structure. Teepee or beehive burners are used to dispose of waste wood in logging yards and sawdust from sawmills by incineration. As a result, they produce a large quantity of smoke and ash, which is vented directly into the atmosphere without filtering, contributing to poor air quality. The burners are considered to be a major source of air pollution and have been phased out i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Particle Board
Particle board, also known as chipboard or low-density fiberboard, is an engineered wood product manufactured from wood chips and a synthetic resin or other suitable binder, which is pressed and extruded. Particle board is often confused with oriented strand board (OSB) (also known as flakeboard, or waferboard), a different type of fiberboard that uses machined wood flakes and offers more strength. Characteristics Particle board is cheaper, denser and more uniform than conventional wood and plywood and is substituted for them when cost is more important than strength and appearance. Particleboard can be made more appealing by painting or the use of wood veneers on visible surfaces. Though it is denser than conventional wood, it is the lightest and weakest type of fiberboard, except for insulation board. Medium-density fibreboard and hardboard, also called high-density fiberboard, are stronger and denser than particleboard. Different grades of particleboard have different densi ...

Environmental Issues In Canada
There are many different types of environmental issues in Canada which include air and water pollution, climate change, mining and logging. Environmental issues based in Canada are discussed in further detail below. Climate change Melting of the Arctic and its effects on marine ecosystems Scientists across the world have already started to notice massive reductions in Canada's Arctic sea ice cover, particularly during the summertime. The shrinking of this ice results in the disruption of the ocean circulation, and changes in climate and weather around the world. The 2019 ''Canada's Changing Climate Report'', written by scientists from institutions around the globe, states that the impacts of climate change on Atlantic Canada will be very diverse. One impact is that the sea ice will become thinner and will also form for much shorter periods of the year. And with less sea ice than the region usually gets now, wave seasons will become more intense. Atlantic Canada will see a rela ...

The Register-Guard
''The Register-Guard'' is a daily newspaper in the northwestern United States, published in Eugene, Oregon. It was formed in a 1930 merger of two Eugene papers, the ''Eugene Daily Guard'' and the ''Morning Register''. The paper serves the Eugene-Springfield, Oregon, Springfield area, as well as the Oregon Coast, Umpqua River valley, and surrounding areas. As of 2016, it has a circulation of around 43,000 Monday through Friday, around 47,000 on Saturday, and a little under 50,000 on Sunday. The newspaper has been owned by Gannett, The Gannett Company since Gannett's 2019 merger with GateHouse Media. It had been sold to GateHouse in 2018. From 1927 to 2018, it was owned by the Baker family of Eugene, and members of the family served as both editor and publisher for nearly all of that time period. It is Oregon's second-largest daily newspaper and, until its 2018 sale to GateHouse, was one of the few medium-sized family newspapers left in the United States. History of ''The Guard'' ...

Clean Air Act (1970)
The Clean Air Act (CAA) is the United States' primary federal air quality law, intended to reduce and control air pollution nationwide. Initially enacted in 1963 and amended many times since, it is one of the United States' first and most influential modern environmental laws. As with many other major U.S. federal environmental statutes, the Clean Air Act is administered by the U.S. Environmental Protection Agency (EPA), in coordination with state, local, and tribal governments. EPA develops extensive administrative regulations to carry out the law's mandates. The associated regulatory programs are often technical and complex. Among the most important, the National Ambient Air Quality Standards program sets standards for concentrations of certain pollutants in outdoor air; the National Emissions Standards for Hazardous Air Pollutants program sets standards for emissions of particular hazardous pollutants from specific sources. Other programs create requirements for vehicle f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Pollution In British Columbia
Air pollution is a concern in British Columbia, Canada because of its effects on health and visibility. Air quality is influenced in British Columbia (BC) by numerous mountain ranges and valleys, which complicate atmospheric pollution dispersion and can lead to high concentrations of pollutants such as particulate matter from wood smoke (especially during stagnant atmospheric conditions/ inversions). Air quality in BC Air quality in much of BC is good compared to many areas of North America. This is particularly true for cities in BC such as the Greater Vancouver area and Victoria. Valley communities such as Golden may experience periods of poor air quality, particularly during stagnant atmospheric conditions. Two communities currently exceed the federal standards for maximum safe levels of pollutants: Prince George for particulate matter (PM2.5), and the community of Hope in the lower Fraser Valley for ozone. Other communities are close to the PM2.5 standard, such as Que ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Louisiana-Pacific
Louisiana-Pacific Corporation, commonly known as "LP", is an American building materials manufacturer. It was founded in 1973 and is currently based in Nashville, Tennessee. LP pioneered the U.S. production of oriented strand board (OSB) panels. Today, LP is the world's largest producer of OSB, and manufactures engineered wood building products. LP products are sold to builders and homeowners through building materials distributors and dealers and retail home centers. As of 2011, LP has 24 mills including 15 in the United States, six in Canada, two in Chile and one in Brazil. History A leading manufacturer and marketer of building and lumber products, Louisiana-Pacific Corporation (LP) revolutionized the industry by inventing alternatives to plywood and solid wood building products.
