Bion’s patented third-generation technology was designed to dramatically reduce the environmental impacts of large-scale livestock production and deliver a USDA-certified sustainable product to the consumer. The platform simultaneously recovers high-value coproducts and renewable energy that increase revenues. Bion’s 3G tech platform can provide a pathway to true economic and environmental sustainability with ‘win-win’ benefits for at least a premium sector of the $175 billion livestock industry, the environment, and the consumer.

What does ‘cleanup’ look like?˃ Water (nutrients), air (ammonia, carbon), pathogens˃ Cost to remediate the environmental impacts is economically

unsustainable in this low margin industry – global export is especially sensitive.

˃ New recurring revenues, premium pricing for branded products and/or subsidies are required.

˃ Improvements must be verifiable by third party.˃ Must be able to communicate improvements to the consumer.˃ Bion’s patented 3G platform supports these requirements for

large scale production of beef, dairy, poultry, swine.

American Biogas Council Praises House Introduction of the GREEN Act

November 19, 2019 - WASHINGTON - The Ways and Means Committee in the House of Representatives has released a discussion draft of the Growing Renewable Energy and Efficiency Now (GREEN) Act including several provisions that support the biogas industry. The Committee describes the bill as “a comprehensive approach to tackling climate change by using the tax code to extend and expand renewable energy use and reduce greenhouse gas emissions.”

IN THE SENATE OF THE UNITED STATESJULY 22, 2021

Mr. BROWN (for himself and Mr. THUNE) introduced the following bill; which was read twice and referred to the Committee on Finance

SECTION 1. SHORT TITLE.

This Act may be cited as the ‘‘Agriculture Environmental Stewardship Act of 2021’’.

˃ Water/ nutrient crisis is worsening– EPA: one of the greatest water quality problems in the U.S. today– Toxic algae blooms, dead zones, groundwater contamination– Climate change will increase runoff

˃ New focus on air pollution: ammonia/ PM2.5, greenhouse gases

˃ Current production practices MUST change˃ Elements of the livestock industry accept their role

˃ Feds implementing policy/ mobilizing resources˃ State policies changing – credit trading/ procurement

˃ Consumer exodus (dairy alternatives, now meat alternatives)˃ 3G Tech platform ready for commercial projects (core optimization

trials completed Feb 2021)

˃ Additional 3G tech patent allowances and filings (ongoing)

˃ 2021/22 policy initiatives. Expected:– PA procurement legislation adopted– Federal cost share implemented– Federal Energy ITC (30%, as in solar and wind) for biogas and

nutrient control technologies˃ Ongoing technology platform R&D/ improvement˃ Seek next round of organic ‘approval’ (App into OMRI)˃ Initiate beef demonstration project (In process)˃ Initiate ammonium bicarbonate plant growth studies (In

Global Livestock19.60 billion poultry

U.S. Livestock2.20 billion poultry90 million beef cattle60 million swine 9 million dairy cows

Perspective: With ~15 million cattle on feed in the U.S. at any given time, Bion’s beef opportunity model (with 150,000 head) represents approximately one percent of the U.S. market.

˃ Bion is NOT BYND, a sexy media-darling that has many hurdles to clear before ECONOMIC sustainability

˃ Disruption in the food supply chain– A plant-based substitute for animal protein– Target is ground meat market (10% of overall market)– Crowded space– ‘Nose-bleed’ valuations

˃ What about the consumer?– Consumer has demanded sustainable, NOT replacement– SHOULD we blow up the current supply chain? What about

everything BUT ground? (the other 90%)˃ Bion’s tech can provide an industry response to anti-meat

messaging and addresses a much larger market˃ Shows Street’s appetite for transformation in the food supply

chain

The livestock industry is changing. It is not ‘going to

happen’. It is happening now.
