Energy-Saving Technology for Renewal of Air-Conditioning Systems in Office Buildings
Energy saving has recently become an urgent issue for office buildings in order to prevent global warming and to respond to the growing imbalance between energy supply and demand. There is an increasing need for the replacement of the old equipment in the buildings that were concentrically constructed in the 1990s with energy-saving equipment.
With this as a background, Toshiba has developed a new air-conditioning system that provides both comfort and energy savings and used it to replace the equipment in the Toshiba building that needed renewal work. We used a renewal method that minimizes the disturbance for the tenants in the building.

Solution for Water Cycle and Resource Recycling

Toward Development and Adaptation of Total Solution Technologies for Global Water Issues

Trends in System Solutions for Global Water Cycle and Effective Use of Resources
Global-scale issues to be addressed include depletion of natural resources, food, water, and energy due to rapid global population growth. Water is consumed in the process of food production, although fresh water is not always available where it is required. Fresh water can be produced from sea water, but this requires energy. Energy is extracted from the burning of fossil fuels, which emits carbon dioxide (CO2), and this causes global warming and will eventually have significant impacts on the global water cycle. A comprehensive approach aimed at a total optimization system is therefore required to solve the complex interactions of these social infrastructure-related issues.
With these trends as a background, Toshiba is making continuous efforts to provide integrated system solutions using its water treatment and resource recovery technologies as well as energy technologies.

HATTORI Dai / SUGINO Toshiharu / YOKOKAWA Katsuya
There is a growing trend toward the expansion of infrastructure in the field of water supply and sewage services due to the merging of municipalities and businesses in recent years. Major waterworks are required not only to adopt centralized control and monitoring systems for operating numerous water facilities but also to realize more effective and economical operations.
To meet these requirements, Toshiba has been providing an advanced supervisory control and data acquisition system for supplying safe drinking water to widespread areas. This system offers several advantages including water distribution network analysis, distribution control simulation, and water operation scheduling technology.

Water Treatment Technology Using New Adsorbent
YAMANASHI Ichiro / KONO Tatsuoki / YUKAWA Atsushi
Toshiba has developed a water treatment technology using a new adsorbent, called a functional powder, that can be selectively adsorbed to both hazardous substances and valuable materials contained in water and sewage. Each adsorbed material can be recovered as a pure substance and the adsorbent can be reused, unlike conventional single-use adsorbents. This water treatment technology can therefore contribute to the recovery of resources from inorganic industrial wastewater treatment systems with high concentrations of certain substances by reducing the cost of processing industrial waste.
We have confirmed the effectiveness of this adsorbent in removing lubricating oil from soluble cutting agents through field tests applying it to waste from a machining process.
