Boart Longyear John Hoffmeister as president and chairman of the board of the company. FACTS was dissolved when Boart International (a wholly owned subsidiary of Anglo American) bought out CDP's interest in Longyear. In 1974, Boart International invested capital which helped Longyear to become the world's leading manufacturer of diamond bits. Boart Longyear engineers in North Bay, Ontario, secured a reliable source of high-performance synthetic diamonds, which triggered the development of a new bit design – the impregnated-diamond bit. With decades of powder metallurgy experience behind them, Longyear engineers set out to develop a new crown that consisted of synthetic diamonds evenly
Waste-to-energy landfilling. Incinerators have electric efficiencies of 14-28%. In order to avoid losing the rest of the energy, it can be used for e.g. district heating (cogeneration). The total efficiencies of cogeneration incinerators are typically higher than 80% (based on the lower heating value of the waste). The method of incineration to convert municipal solid waste (MSW) is a relatively old method of WtE generation. Incineration generally entails burning waste (residual MSW, commercial, industrial and RDF) to boil water which powers steam generators that generate electric energy and heat to be used in homes, businesses, institutions and industries. One problem associated
