The Kyocera group understands the importance of industries doing their part to help save our planet by going green. They know that conserving energy not only benefits their companies by reducing costs, but it is also beneficial to the environment by reducing the carbon footprint.

To keep its buildings more energy efficient and their greenhouse emissions low, the makers of IT equipment and industrial ceramics have installed “green curtains” at 20 of their manufacturing and office buildings at facilities in Japan, Thailand and Brazil.

Thousands of feet of edible “green curtains” cover the walls of their buildings keeping them shaded and cooler, lowering the temperature by as much as 27°F and 15°C while absorbing approximately 23,481 pounds of carbon dioxide emissions.

Another amazing aspect of this incredible “green curtain” is that the 32,750 square feet of the energy-saving greenery is truly edible. It’s a double positive serving the dual role of effective energy saver and organic produce supplier. Every curtain provides fresh vegetables for Kyocera employees to enjoy in their cafeterias including cucumbers, peas and goya gourds.

Kyocera invites everyone to be more eco-friendly by implementing green solutions at home. By taking a few energy-saving measures such as recycling, setting thermostats lower, conserving water with low-flow faucets, using filtered rather than bottled water, using non-toxic cleaning products and disposing of e-waste properly, it is possible not only conserve energy which is good for the planet, but also to save money which is good for everyone.

Growing a “Green Curtain” in Six Simple Steps:

Prepare the Soil

Place a layer of stones on the bottom of soil-filled planter.


Plant the seed into the soil and water immediately. If you use seedlings it will set the roots more firmly and the foliage will grow faster. Germination usually takes 2 or 3 weeks and we recommend if you are growing goya, seeding should be started from the middle of April to beginning of May, and from the end of April to beginning of May for seedlings.

Constructing the Netting

It is recommended to use a stake or a pole to stabilize the netting at the top and bottom. Extend the netting as far across the wall as possible to allow the plant to provide plenty of shadow. This will make the “Green Curtain” more effective in preventing the rise in room temperature.


Water twice a day in the mornings and evenings or according to climate and local weather needs.


After initial planting, add in fertilizer every 2 weeks taking care not to add too much. Adjust the amount of additional fertilizer used depending on individual growing conditions.


Green Curtains will be formed from around the end of June to the beginning of July. You can also enjoy harvesting home grown vegetables, flowers and other favorite healthy growing plants.

When it comes time to harvest the produce you have grown with your own edible “green curtain” you will want to preserve its fresh homegrown taste by using premium cutlery. Kyocera makes the perfect prep tools for slicing vegetables, fruits and other ingredients that will not transfer smell or flavors. Their long lasting ceramic blades are bacteria resistant, rust free and need to be replaced less often, making them not only healthier than stainless steel but more eco-friendly as well.
