Bion’s unique and patented Ammonia Recovery System (ARS) captures and stabilizes the volatile ammonia freed up when biogas/RNG is produced from an organic waste stream, like animal manure, food and food processing waste. It transforms the ammonia, a serious environmental liability, into a high-value organic nitrogen fertilizer that can be precision applied when and where needed. The ARS can be used as a standalone ammonia control solution for biogas production or anchor a comprehensive waste treatment and resource recovery platform for large-scale livestock production. Bion's tech was developed for the livestock industry, that is under the microscope for its substantial environmental and public health impacts. A comprehensive Bion platform can largely eliminate the environmental impacts of large-scale production while improving operational and resource efficiencies by recovering valuable fertilizer products, renewable energy and clean water from the waste stream. Bion’s unique and patented technology platform can help transform both the $175B U.S. animal protein sector and the way we manage our soil, air and water quality. Bion's patents were recently extended to industrial and municipal waste streams, in addition to animal manure waste, and the Company is exploring its opportunities in those sectors.

We empower Arizonans to work together toward more verdant, equitable and sustainable communities. We share a deep concern about sustainability issues and work to increase knowledge with a focus on education in the following areas: -Develop and demonstrate cutting-edge and innovative solutions to environmental issues. -Provide Arizona residents with simple, manageable solutions to address everyday needs in a more sustainable manner. -Promote and support existing sustainability initiatives to ensure that every Arizona resident understands their impact on the environment.

The US Biochar Initiative (USBI) is advancing the production and use of biochar in industrial, agricultural and infrastructure markets to reduce biomass waste, grow the economy, and mitigate climate change. Biochars are fine-grained, highly porous charcoals that help soils retain nutrients and water. Biochar saves water. Biochar reduces dependency on chemical inputs. Biochar is an investment, not a cost. Biochar is decarbonizes the built environment and heavy industry. Biochar carbon can be used in construction, as filler, as pigment, as building element to reduce embodied carbon in everyday items. We can utilize above ground resources to solve many of our carbon removal and carbon management concerns. USBI hosts meetings, conferences, and workshops to discover practical uses of biochar in North America. Recent projects include: market studies; education materials; networking; demonstration projects; and coordination with sectors interested in research, production, and use of biochar including agriculture, forestry and wood product, biomass energy, organics recycling, building products and ecosystem services. USBI is a partner with the International Biochar Initiative and collaborates with other biochar organizations around the world. Our vision is a thriving biochar industry that supports resilience and decarbonization in agricultural, industrial, and infrastructure systems while sequestering carbon, growing the economy, and building sustainable circular systems. Join USBI at our next North American Biochar Conference, September 2025, in Minneapolis, MN.
