Green technology can be defined as a new solution that must be applied to preserve nature and reduce pollution. The world of “green technology” encompasses methods and materials forming techniques to generate energy for non-toxic cleaning products. Green technology has the elements of sustainability, “cradle to cradle” design, source reduction, innovation, and viability. Being sustainable means that green technology has to meet the needs of society in such a way that it can continue indefinitely into the future without damaging or depleting natural resources or jeopardizing the future generations’ needs.

Through the “cradle to grave” cycle, any manufactured products should be fully recycled, reclaimed, or re-used. Along any production process, waste generation and pollution should be minimized by changing patterns of production and consumption at the source. The innovations in green technologies have been demonstrated to damage the health of humans and the surroundings.

Phytoremediation is a remediation technology that uses various plants to degrade, extract, contain, or immobilize contaminants from wastewater and soil. This technology has been receiving attention lately as an innovative, cost-effective alternative to the more established treatment methods used at hazardous waste sites. it has been proposed as green biotechnology, that facilitating the elimination of environmental pollutants from wastewater and soil. This strategy can be an alternative green technology method for the remediation of contaminated soil and water.

Phytoremediation group in PPTC has initiated to make use available native plants surrounding Tasik Chini, especially aquatic plants, to imitate the role of natural wetlands in Tasik Chini in cleaning the lake water to clean-up or remediate soil and water from heavy metals, micropollutants, nutrients, and heavy metals. Among identified potential plants from Tasik Chini includes Lepironia articulate (Kercut), Scirpus grossus (Menderong), Eleocharis ochrostacys (Purun), Nelumbo nucifera (Teratai), and Scirpodendron ochrostachys (Selinsing).

Biogas, another green technology, is an environmentally sustainable energy source that contains 50-70% methane and 30-50% carbon dioxide as well as small amounts of other gasses including hydrogen sulphide. The purpose of producing biogas is to reduce the number of agricultural waste resources for examples crop straws and animal manure. Normally, this waste is burnt at random, discarded or directly discharged into the environment, which results in pollution. Biogas research in PPTC is now compiling a biogas database in collaboration with the industry. We hope to produce clean energy and clean up the agricultural and domestic waste in the watershed.
