Idea - Near bodies of water (oceans, lakes, rivers) where unwanted algae blooms flourish seasonally, build oil-producing manufacturing facilities which utilize algae that is deliberately produced in or near those facilities as a raw material resource.

Run these manufacturing facilities 24/7 as regular oil-producing operations and where algae is deliberately grown and then used to manufacture oil, and where the spent algae is used to produce marketable fertilizers. Then, when unwanted algae blooms appear in the adjacent bodies of water, continuously siphon off the algae-infested water, strain the unwanted algae out, return the clean water to the adjacent water body, and then "add" that "strained and unwanted algae" to the 24/7 manufacturing operations that already depend on algae grown in or near those facilities. Thus, rather than eliminating the unwanted algae, which would constitute an un-reimbursed "societal expense," oil manufacturers could turn the unwanted algae into a low-cost and profitable raw material source.

The reference below discusses the science behind producing usable oil from algae in a brackish water medium. Other research has demonstrated the same effect in a fresh water medium.

Research carried out by a group led by Professor HASUNUMA Tomohisa and Academic Researcher KATO Yuichi, both from the Kobe University Graduate School of Science, Technology and Innovation demonstrated that microalgae can grow with light, water, carbon dioxide and a small amount of minerals, and that their cells divide quickly, meaning that they can be harvested faster than land-based biomasses.

Many species of algae are capable of producing large amounts of oil (lipids), but this is the first time that researchers have captured the metabolic changes occurring on a molecular level when lipids are produced in algae cells.

Focusing on marine microalgae, Professor Hasunuma's group found that Chlamydomonas sp. JSC4, a new species of green alga, combines a high growth rate with high levels of lipids. The research team developed an analysis method called "dynamic metabolic profiling" and used this to analyze JSC4 and discover how this species produces oil within its cells.

JSC4 has a high cell growth rate, and the lipid production rate in the culture solution achieved a speed that greatly surpassed previous experiments.

Using dynamic metabolic profiling, the group found that the sugar biosynthesis pathway (activated when starch is produced) slows down, and the pathway is activated for synthesizing triacylglycerol, a constituent element of oil. In other words, the addition of seawater switched the pathway from starch to oil production. They also clarified that the activation of an enzyme that breaks down starch is increased in saltwater solution.

The discovery of this metabolic mechanism is not only an important biological finding, it could also be used to increase the production of biofuel by improving methods of algae cultivation. Based on these findings, the team will continue looking for ways to increase sustainable oil production by developing more data.

    I founded Plastic Technologies, Inc. ( 35 years ago and have spent 40 years in the plastics industry designing, manufacturing, and selling plastic packaging to the major beverage, food, and personal care product brand owners. I therefore recognize the tremendous value that plastic packaging has meant to the world's food, healthcare, and personal care products industries. However, I also recognize the magnitude of the contemporary global disposable plastics waste issue which caused us, 30 years ago, to found Phoenix Technologies International LLC ( which remains today one of the largest merchant PET plastic recyclers in the US, in order to help solve the single use plastics disposal problem. Over my career, however, I have come to recognize that the one thing that is missing from creating a successful universal recycling system is that we have never been able to incentivize consumers, universally, to engage in returning their recyclable disposable plastic items and to clean and separate those items so that recycling can be both successful and economical. My idea of utilizing the "lottery mentality" as an incentive is both novel and proven. I want neither personal credit nor personal recognition for this idea but, if I can get someone or some organization in the country to recognize the power of this idea and to find a way to commercially try/pilot this idea, then my entrance into this "Create the Future" contest will be the only recognition I need.
