Northern Technologies International Corporation (NTIC), MN, in collaboration with Michigan State University (MSU), MI, pans to formulate and engineer chemically modified, marine biodegradable, biofiber-based, non-plastic waste bags that are water resistant, readily treatable with other organic wastes in the on-board waste processing equipment and marine biodegradable as defined by ASTM D7081 standard. As part of Phase I, NTIC investigated (1) three classes of biobased, non-plastic materials that function as a coating or as an adhesive depending on the manufacturing process employed; (2) coating of selected paper substrates using silylated soyabean oil to provide new biobased hybrid composite and (3) conducted aqueous biodegradability testing per ISO 14852. Phase I work was successful in coating soya-based non-plastic material onto different grades of unmodified paper to obtain a water-proof and grease-proof paper. Phase II will be directed toward scale-up and process development of coating paper in a large-scale manufacturing set up and convert the coated paper to bags. Development of such a high strength, water-proof, marine biodegradable, and non-plastic waste disposal bag will assist the fleet in reducing their at-sea plastic usage and significantly decrease the volume of plastic waste that must be processed and stored aboard. Furthermore, the newly developed technology would find application in traditional markets for coated paper such as disposable foodservice ware and trash bags.

This Small Business Technology Transfer Research (STTR) Phase II project proposes to
formulate and engineer chemically modified bio-based and biodegradable Poly(Lactide) based
compounds, to generate a new class of materials that are, high strength, lightweight,
multifunctional, environmentally friendly & cost-effective as an alternative to petroleum based
polymers. NTIC has successfully commercialized a portfolio of reactive blended bio-based
and/or biodegradable resins for extrusion, molding, and coating applications. However, it faces a
major hurdle due to poor mechanical properties, high prices, and higher densities of current PLA
materials. NTIC successfully developed novel chemistries of compatibilization to create
advanced PLA bio-resins that offer improved toughness in Phase I of this work. The newly
synthesized materials were applied in four different processing platforms to provide extruded
films, injection molded cutlery, extrusion coated paper, and extrusion blow molded bottles.
Phase II funding will allow NTIC to build on the success of the initial trials and build an
improved, broader portfolio of high strength and economically viable PLA based products.

The broader impacts of this research are technical, environmental, and
economical. This work will (1) widen the window of performance of PLA based applications; (2)
further fundamental understanding of PLA and its chemistries (3) greatly increase the use of
biobased products in larger industrial and packaging markets implying environmental
preservation of fossil fuel resources; and (4) create new jobs for sales, manufacturing, technical
support of newly developed Natur-Tec® products.

Hydrogen is produced from methanol and water under supercritical temperature and pressure conditions desirably without any catalyst. The hydrogen can be produced in situ on an internal combustion engine using a heat source such as the exhaust system of the internal combustion engine to achieve the supercritical temperature.

A system for protecting storage tank soil side bottoms against corrosion includes a pipe system comprising non-perforated inlet pipes and perforated pipes connected thereto. A sleeve container having solid VCI compounds therein is inserted into the perforated pipes. The sleeves are permeable to vapors emitted by the solid VCI compounds and flow through the pipe to a perforation where they are admitted into an area beneath a storage tank so that they can contact the tank bottom (soil side) and protect the same from corrosion. Alternatively, solid SCI compounds can be used in combination with VCI compounds. The corrosion protection system is designed to be used with aboveground storage tanks. This includes, but is not limited to, single bottom tanks: newly installed or existing tanks undergoing bottom replacement or installation of double bottoms. These tanks are located on substrates such as the compacted soil/sand or hard substrates such as concrete, bitumen mixtures and asphalt where channels can be cut into the substrate for installation of the pipe system.

A method and apparatus for the corrosion protection of tank soil side bottoms is achieved by providing equipment to an existing storage tank as by installing a chime delivery system about the perimeter of the storage tank bottom plate, and introducing an appropriate amount of a corrosion inhibitor into the chime delivery system, whereby the corrosion inhibitor is readily admitted into the spaces between the substrate and the tank bottom plate. The system avoids any refurbishment of the tank and allows for easy introduction and replenishment of inhibitor without interruption of tank operations. The system also does not require any renovation of the tank, and does not require any replacement of the tank bottom plate panels.
