Brewer’s spent grain (BSG) is the main by-product of the brewing industry.

Every six-pack of beer produces about one pound of BSG waste, equating to 20 billion pounds in the U.S. every year. Spent grain is often landfilled or, at best, used as animal feed.

Difficulties of Brewer’s Spent Grain

• High moisture content (70-80%) makes traditional BSG hard to store and heavy to transport

• Common methods of drying aren’t feasible: freeze-drying is too expensive and heat drying is energy-intensive and damaging

Benefits of GTF-Powderized BSG

• The GTF RENU™ Drying and Milling System is able to capture the high fiber, protein, and antioxidants naturally found in BSG, while removing up to 95% of the moisture

• Our technology easily converts spent grain into nutritious flour, ready for resale

Unlike traditional plastics, hemp reduces the greenhouse effect by absorbing carbon dioxide and converting it into oxygen.

Hemp is a renewable resource that prevents soil erosion, thereby reducing water pollution. The resulting bio-plastics from powderized hemp can be used for everything from automobile parts to straws and tableware. So why doesn’t everyone make and use hemp plastic?

Difficulties of Current Hemp Processing 

• Produces larger particle sizes that are difficult to blend with plastics

• Excess water and oil are not sufficiently dried off, creating gumming and jamming the plastic injection molding gates

• Requires slow speeds and high temperatures, reducing throughput and compromising material integrity

Benefits of GTF-Powderized Hemp

• Smaller particles produced at low temperatures

• Quick, single-step, energy saving process

• Results in oil/water content of less than 3%

• Grit-free, nutrient dense, hemp protein powder can also be sold to nutraceutical market

Landfill costs are skyrocketing.

Combined with concern over greenhouse gasses and increased regulations on food disposal, this has incentivized many institutions and governments to search for more effective ways to handle food waste.

Difficulties of Landfilling Food Waste

• Tipping fees can be expensive

• Transportation to landfills is cumbersome and expensive

• Illegal in a growing number of countries, states, and municipalities

• Contributes to greenhouse gasses

Benefits of GTF-Powderized Food Waste

• Removes over 90% of moisture from food waste, drastically reducing its weight and volume before transporting

• Stabilizes material, preventing harmful chemical or greenhouse gas production

• Even if resulting powder is landfilled, it’s space-efficient and will decompose without harming the environment

• Can be upcycled into biofuel and natural fertilizer

Leading-edge governments and universities are composting their food waste.

Whether on their own or with the help of professional composting companies, composting is becoming more popular with big organizations.

Difficulties of Composting

• Time-consuming: Takes four months or more to convert food waste to compost

• High-maintenance: Must be agitated regularly to aerate

• Can be odorous

• Requires acreage

Benefits of GTF Milled Alternative

• Takes seconds to do what nature does in months

• Removes over 90% of moisture from food waste, drastically reducing its weight and volume before transporting

• Equipment is space efficient (<1,000 ft²)

• Stabilizes the material, eliminating odors and preventing harmful chemical or greenhouse gas production

• Resulting powder can be upcycled as animal feed or fertilizer

• Even if does end up in a landfill, the powder is compact and will decompose without harming the environment
