Environment
Reducing the Environmental Impact of Plants
In order to meet rigid environmental standards put in place by customers and local environmental regulations, we need to reduce the environmental impact of products and plants. NHBB does this in line with its Sustainability Roadmap through a wide range of environmental activities. To save energy, NHBB has introduced reflective coatings and high-efficiency cooling systems, and has set a target of reducing CO2 emissions 5% by 2015 (based on 2010 levels). To save resources, the company has stepped up recycling of cutting fluid and plastics as well as improvements to cleaning systems.
NHBB applies the experience acquired through these activities by playing an active role in environmental policy formulation for New Hampshire. In 2009, we were part of a task force responsible for developing the state's Climate Action Plan. The Climate Action Plan is still used as a roadmap for the state's environmental activities.
Introduction of "re:cool" Coolant Recycling System
A scene from the recycling process
NHBB uses a system called "re:cool" to make effective use of coolant and metal emitted during the bearing grinding process. Coolant reuse was previously complicated by fine metal swarf in the used fluid. Using "re:cool," coolant and swarf are separated and briquettes are created to enable recycling of the metal. The system also enables completely closed recycling of coolant, which is reverted to its pre-use state through processes such as centrifugal separation and filtration. As a result, NHBB has managed to reduce annual disposal of coolant by around 5,700 liters and increase the volume of metal sales. This success has prompted us to recommend the system to suppliers.
Efforts to Conserve Water Resources
In California water resources are scarce and reducing water usage is a major issue. NHBB has taken action to reduce the amount of water used in the product cleaning process by switching cleaning agents. Annual water usage has been halved as a result. Now we are planning to reduce water usage further by switching to environmentally friendly solvents for other processes that use water.
