Alto Plant-based Plastic Recorders
Materials that are gentle on the environment
Bodies made of plant-based “Ecodear” plastic: the world’s first application* of environmentally friendly plant based materials in a musical instrument. * As a musical instruments commercially available, according to our own research in June 2014.
Improved instrument performance
The change in material has resulted in a mellow, centered tone that is similar to that of wood recorders, plus improved breath response and high-register control.
Plant-based plastic “Ecodear”
"Ecodear" plastic is a plant-based material created by combining polylactic acid (PLA)* derived from plants with other materials through an original Toray polymer alloy process, achieving characteristics that are similar to conventional oil-based resins.* Plant-based PLA Compound ResinPlant-based PLA compound resin is produced from plant starch (corn is the main ingredient currently used) via a process that includes lactic acid fermentation and polymerization.The "Ecodear" used in the YRS-401 and YRS-402B recorders is a compound of polylactic acid and ABS resin (3:7 ratio) that has about the same workability, durability, strength, and appearance as conventional ABS resin, while reducing CO2 emissions by approximately 20%. CO2 emission for the production of 1,000,000 recorders is reduced by approximately 230 tons: equivalent to the CO2 that would be produced by a car*1 traveling around the earth 25 times.*2 *1: 10 liters/100 km gas mileage. *2: The circumference of the earth is approximately 40,000 kilometers.“Ecodear” is a safe material that has been used in home appliances, office equipment, and a variety of other items.
Why is plant-based plastic gentle on the environment?
1. Reduced CO2 emissionsPlants grow by absorbing CO2 that would otherwise add to the global warming problem. Even though plant-based plastic results in the same CO2 emissions as other materials during manufacture, use, and disposal, the total amount of CO2 produced is reduced by the amount absorbed during growth.2. Reduced use of oilOil is the main raw material used in plastics, but reserves are limited and will be depleted in the not-so-distant future. By replacing a portion of the raw material requirements with plant-based materials the total amount of oil used can be reduced, thereby prolonging the availability of fossil resources.
Certified as Yamaha Eco-Products
Plant-based Plastic Recorders are certified as Yamaha Eco-Products, which is a certification established by Yamaha for products that meet the standards of “Product Environmental Quality Objectives”.
Artist Comment: Kuricorder Quartet
“The ‘pop’ colors are great! The weight is right for a musical instrument, and the tone is seriously musical too. The resistance is comfortable, and you can play hard. Notes in the high register are particularly easy to produce. Note definition is good and tonguing is easy. The notes have a well-defined center. This soprano recorder plays beautifully. There is very little variation from instrument to instrument, so these will be great for recording unison parts. The fact that just changing the material has resulted in such a noticeable improvement highlights the depth of the recorder as a musical instrument. The improvement in the rate of development of children who start with these recorders is likely to be significant."
German and Baroque fingering systems
Yamaha offers a choice of either “German” or “Baroque” fingering systems on many models to accommodate local preferences and traditions.German system: YRS-401Baroque system: YRS-402B, YRA-48B/402B
