Improving the Resource Efficiency and Resource Circulation of Products

Our Approach

There is a growing view worldwide of the importance of resource efficiency. An example can be seen in the EU's designation of resource efficiency as a growth strategy and its establishment of the Resource Efficiency Flagship Initiative.

Efficient use of resources in the ICT products that we provide to customers is important. We have engaged in 3R design that draws on the principles of reduce, reuse, and recycle, and have developed our products with technology that is effective in reducing the use of resources. We are making efforts to improve resource efficiency, which is made possible by designing products to be lighter and smaller, using recycled plastics, reducing the number of parts, enhancing ease of disassembly, and improving recyclability. Our goal is to offer products that provide customers with benefits including compactness, light weight, and space savings.

FY 2017 Performance and Results

Summary of FY2017 Achievements

Improving the Resource Efficiency of New Products

In FY 2012, the Fujitsu Group created its own definition of resource efficiency. In FY 2017, as well, we continued to use our indicators to evaluate products newly developed by Fujitsu*1, while also reducing product part quantities and reducing product size through smaller, thinner, and lighter parts and higher-density mountings.

*1 Products newly developed by Fujitsu:
Excludes products for which resource efficiency is determined by customer specifications or standards.

Achieving 23.1% Improvement in Resource Efficiency

Fujitsu has achieved a 23.1% improvement in FY 2017, against a target of 10%, through reduced size and weight, in PCs, smartphones, mission critical x86 servers, POS tenant devices, mobile phone radio base stations, etc.

Working toward Our Targets

To improve new product resource efficiency by at least 15%, Fujitsu will continue current initiatives, while expanding development of new lightweight, rigid materials and the use of recycled materials. We will also widely publicize product environmental performance to grow sales.

Main Activities in FY 2017

Mission-critical x86 servers featuring both high-performance and compact housing

Resource Efficiency 70%

The 8-socket IA server PRIMEQUEST 3800E maintains world-class performance while also inheriting the high reliability and high availability of the mainframe class. At the same time, it features a compact housing and lightweight design made possible by improved cooling performance and a high-density PSU. The weight was reduced by 41.3%.

Cooling performance was improved by reviewing the CPU heatsink design and improving heat dissipation for the overall heatsink. Furthermore, through improvement of the inlet flow balance made possible by revising the housing layout and duct structure, the heat radiation capacity has been significantly increased. This made it possible to reduce the size of the CPU heatsink to one-fifth of the original.

Furthermore, by using a high-performance contra-rotating fan for the cooling fan, the airflow per unit volume was increased by 1.8 times. The density of the PSU was increased by revising the cooling method and implementing high-efficiency technology. PRIMEQUEST 3800E achieves four times the power density compared to the conventional product (PQ2800E). Through these initiatives, we succeeded in greatly reducing the size of the server.

13.3" notebook PC achieves the world's lightest weight for the second consecutive year

Resource Efficiency 101%

For the second consecutive year, LIFEBOOK UH75/B3 was the world's lightest 13.3" notebook PC. The previous model that was released in 2016 weighed 761 grams, while the new model released in November 2017 was 13 grams lighter, achieving a weight of 748 grams.

Compared to the previous model, we achieved a 9-gram reduction by revising the structure of the battery case frame. For the housing cover, we cut multiple concentric shapes inside the cover and reduced the cover thickness. These changes reduced the cover weight by a total of 4 grams. Furthermore, by using magnesium alloy in the housing top surface, bottom surface, and wrist rest cover, we achieved a strong design in conjunction with the light weight.

Advancing 3R Design

Through our proprietary product environmental assessments and green product evaluations, the Fujitsu Group is working toward the application of reduced resource usage, improved recyclability, and other technologies that take into account the 3Rs. Examples of the effective resource-saving technologies that we are deploying in our products include reductions in the number of components and cables, performance enhancements, space savings through higher-density integration, and digital product manuals. Furthermore, we are using Fujitsu's own 3-D Virtual Product Simulator (VPS), which is popular with many of our customers during their product design processes, to test the steps involved and the convenience of product assembly and disassembly before creating prototypes.

From 2010, we have also conducted regular study tours for designers at the Fujitsu Group recycling centers. In addition to hands-on experience with dismantling used products, designers gain feedback from staff in charge of recycling through idea exchanges and explanations of the obstacles to ease of dismantling. From FY 2015, the Fujitsu Group has been summarizing examples of the obstacles to ease of dismantling that we have learned from some 90 case studies at 5 recycling centers. Results are distributed in a systematic collection complete with pictures.

Eco-Friendly Packaging

Fujitsu is working on a variety of methods for reducing its use of packaging and cushioning materials. Conventionally, a notebook computer is shipped individually packed in a cardboard box, but now, by packing several products in a single returnable container, we have reduced shipping space and cardboard waste. For larger products, we have replaced conventional cushion foam with returnable air packs. With this new packaging style, we are repeatedly using packaging materials, and can use the same materials for various products. Greater efficiency in the use of packaging materials has reduced the amount of cushioning materials and wastepaper shipment, thereby, significantly reducing CO2 emissions. We also use vegetable oil inks, which are lower in volatile organic compounds (VOCs), a known atmospheric pollutant, to print the boxes used for packaging PCs and other equipment.
