Chlorine Dioxide Plant In May 2015, CMPC Celulose Riograndense, a subsidiary of Chilean CMPC in Brazil, successfully started its new 1.3 million tonnes/year bleached eucalyptus kraft (BEK) pulp line at Guaíba, in Rio Grande do Sul state. This pulp mill expansion included a new 55 tonne/day chlorine dioxide plant, supplied by Chemetics (Vancouver), a subsidiary of US-based Jacobs Engineering Group.

Wire Theft Abatement Since 2005, the City of Surrey has experienced a dramatic increase in copper wire theft from its free-standing ornamental street light system. Over the past 10 years, the City spent approximately $9.8 million in direct repair costs. To curb this illegal, unsafe activity, the Engineering Department undertook a technical review and a business case study for replacing the conductors from copper to aluminum. Since aluminum has approximately 10% of the value of copper on a weight basis in relation to selling it through recyclers, there would be little incentive for wire theft. Both the technical review and business case supported the replacement of the streetlight conductors from copper to aluminum. In 2014 the City of Surrey, with inspection and coordination services by Aplin & Martin Consultants, commenced a city-wide Wire Theft Abatement Program and replaced approximately 700 kilometers of streetlight wires from 16,000 free-standing ornamental lights within one year. Client: City of Surrey. Consultant: Aplin & Martin Consultants.
