To celebrate Earth Day, we want to focus on sustainable, environmentally friendly technologies.

This year, we wanted to focus on inventions related to recycling. Recycling is the top action society can do to improve the environment, the economy and sustainable manufacturing. Below are some well-known green inventions that are changing our world.

Apparatus for Amplifying Solar Energy by Recycling Greenhouse Gas (U.S. Patent Application No. 20140102439)

Solar energy, a renewable form of energy, can be collected all over the the world. Additionally, it can generate electricity in large quantities.

For this invention, inventor Yong Lee developed a way to cut down on the complexity of generating energy through solar means while also utilizing greenhouse gases. The application, filed in 2010, describes this invention as consisting of a sealed compartment through which greenhouse gases can flow. When exposed to sunlight, the greenhouse gas can be used as a way to providing heat to water.


City Parks for Resource Recycling and Green Revolution (U.S. Patent No. 20140083937)

Freshwater makes up a small fraction of all water on the planet. While nearly 70 percent of the world is covered by water, only 2.5 percent of it is fresh. The rest is saline and ocean-based.

To help with water scarcity issue some areas face, the Tarim Resource Recycling Company of England came up with a water recycling system. The system has the added benefit of using carbon emissions to recycle wastewater into biologically cleaned water, making it OK to drink in communities throughout the world.

Portable Recycling Center (U.S. Patent No. 8684437)

The goal of any recycling center to make recycling easier and accessible for individuals.

Inventor Jeff Collins came up with a portable recycling center housed in a multipurpose trailer. The trailer recycling system includes rollers, articulated booms and other means for collecting recyclables from individuals and depositing them into various compartments. The trailer also includes a storefront section with office space, bathroom, fresh water tank and other useful amenities.

Whether you’re learning about solar energy or taking advantage of your city’s recycling program, there are numerous ways technology and innovation is helping restore our Earth.
