Manufacturing processes with smaller environmental loads
Roland regards technologies that make effective use of limited energy resources as "Energy Saving Technology" and promotes development of environment-conscious electronic musical instruments that incorporate such technologies in any of the product categories.
Beautiful music, beautiful planet –
- The "JUNO-Di" mobile synthesizer and the "AX-Synth" shoulder synthesizer as well as the "Lucina AX-09" synthesizer have achieved power saving which was a challenge in synthesizers having professional sound quality, by means of our exclusively developed high efficiency circuits, thereby enabling the synthesizers to be powered with rechargeable batteries that can be used repeatedly.
- The "BA-330" stereo portable amplifier has enabled powerful PA sounds to be enjoyed even in places where no power supply is available, by means of power-saving battery technologies. Also, the "BA-55" portable amplifier that adopted a small-sized and lightweight design comes bundled with a digital wireless microphone that provides high quality sounds. This battery-powered system has achieved loud sounds with a sound pressure level of 108 dB whereby powerful sound reverberates even in a hall accommodating 60 - 80 people.
- The "R-05" recorder that fits snugly in the palm of your hand enables high quality sounds to be recorded easily with a high quality sound design and simple operability. It provides recording to SD/SDHC memory cards, enabling continuous recording for more than 16 hours with two size AA batteries. (The "R-05" won the Good Design Award 2010.)
- The "KC-110" is the world’s first AA battery-powered stereo keyboard amplifier. It features 30 watts (15W+15W) stereo amplifier with two 6.5" custom speakers and two tweeters, and enables a wide range of keyboard sounds to be played back with projection that is unimaginable from its compact design.
- The "AC-33" amplifier for acoustic guitar is rich with functions such as high-quality stereo effects, antifeedback, and looper, etc. It can run on batteries and plays back the rich sounds of acoustic guitars in a natural manner in any place.
- The electronic piano "HP505" has achieved a 58% reduction in power consumption as compared to previous models, by means of a combination of specially designed high efficiency power supply amplifier and speaker system while delivering powerful sounds.
Manufacturing processes that do not use hazardous chemical substances
As restrictions come into effect globally regarding the use of designated chemical substances that can cause environmental pollution, Roland is working towards gathering the latest information on environmental laws in Japan and other countries, carrying out ongoing verifications of the legality of our products and technologies, and developing and designing products in ways that eliminate the use of hazardous chemical substances.
Some regulations on chemical substances regulate hazardous substances that are used and discharged during the manufacturing process. We have created a set of stringent internal standards (List of Chemical Substances Whose Use in Products is Prohibited or Restricted) to reduce the amount of hazardous chemical substances used, and to implement appropriate controls.
Industrial waste reduction and recycling
Roland has set waste material recycling rate targets of 85% or higher and 73% or higher at the head office factory and the Miyakoda factory respectively. Waste material are sorted, disassembled, and separated to promote recycling.
* The reason for a decrease in recyclable wastes in the head office factory in the period ended March 2012 is that we took initiatives to transform waste pallet into organic soil following Miyakoda factory. It has achieved a 35% reduction in total weight of recyclable wastes as compared to previous period ended March 2011.
Activities for reducing CO2 emissions
Also, replacement of equipment and lightening devices with that of the low power consumption type and ongoing energy-saving activities in daily work are operated, and in the period ended March 2012, the power consumption in the head office factory decreased by 21.4% and by 22.2% in the Miyakoda factory over the previous period.
* Calculations were based on the nationwide harmonized CO2 conversion factor (0.559kg-CO2/kWh) defined by the Ministry of the Environment.
* This value was calculated using the conventional ton-kilometer method based on the CO2 emissions factor for volumes transported by ship as defined by the Ministry of Land, Infrastructure, Transport and Tourism.
