미국에서 가장 큰 잔여유기물 재사용업체인 Synagro Technologies가 최근 톨레도 시의 바이오고형물 재활용 5개년 프로그램의 세부사항을 발표했다. 톨레도 시는 상업 화학 비료의 사용을 줄임으로써 에리호 분수령의 수질을 향상시킬 계획이다.

바이오고형물 재활용 프로그램의 강점 및 이점은 다음과 같다.

·톨레도 시의 바이오고형물은 농장에 천연비료로 사용될 예정으로, 강이나 호수 등으로 유출될 잠재적 위험을 가진 400톤 이상의 화학 비료를 필요로 하지 않게 된다.

 

 

 

Synagro Technologies, the nation's largest recycler of organic residuals, recently announced details of a five-year biosolids recycling program in the city of Toledo, Ohio, that will improve water quality in the Lake Erie watershed by reducing the use of commercial chemical fertilizer.

 

Highlights and benefits of the biosolids recycling plan include the following:

·Toledo's biosolids will be used as a natural fertilizer on farmland, eliminating the need for more than 400 tons of chemical fertilizer, which has greater potential of runoff to rivers, lakes and streams.
·The use of biosolids as fertilizer will reduce the potential for phosphorus runoff to waterways by 98 percent.
·The fertilizer will benefit local farmers by avoidance of costs of commercial chemical fertilizer at a rate of $100 per acre of farmland.
·There will be an improvement of water quality through an ongoing, proactive nutrient management program on farm sites.
·Full compliance with Ohio's rigorous environmental regulations will occur regarding biosolids application and nutrient management.
·A savings for taxpayers of more than $900,000 per year versus landfill disposal of the biosolids will also take place.

 

As part of the biosolids recycling program, Synagro will have a qualified agronomist/certified crop advisor on staff to work with the farming community, engaging with farmers by soil sampling, sharing best practices on nutrient management and providing an organic alternative to commercial fertilizers.

 

Synagro's technical staff will also permit the land application sites, work with the operations teams to ensure placement of the biosolids using sustainable practices, and conduct public outreach meetings with the local farming communities and general public.
