蓝莓视频 researchers are combining alpaca waste with biochar to design a new compost that helps people and the planet
Tucked between 蓝莓视频 and Hamilton, is home to a herd of alpacas plus owner and farmer Frances Stewart. After years of caring for her animals, Stewart has teamed up with researchers in the Faculty of Environment to unlock surprising new possibilities for alpaca waste.
Waste fiber, the shearing from the neck, belly and legs of the Alpaca, is often too short and coarse to be used in the mill. Farmers use some of this waste fiber in their garden to help the soil retain water, but excess is often burnt or stored. Then there is also the question of manure, and lots of it.
With these two waste problems mounting, Francis approached Dr. Maren Oelbermann, professor in the Faculty of Environment who leads the . The group is dedicated to improving soil health 鈥� and by extension, food security 鈥� in the age of climate change and were intrigued by Stewart鈥檚 dilemma.
鈥淲hen I thought of using the waste fiber in a more productive way, I was interested in pelletizing it similarly to what they do with sheep鈥檚 wool,鈥� Stewart says. 鈥淏ut alpaca fiber does not bind as a pellet because of the lack of lanolin and would require a binding agent; hence combining it with manure.鈥�
鈥淲ith the research group鈥檚 expertise, we thought developing a specific fiber-to-manure ratio could offer farmers a natural, effective alternative to chemical amendments, potentially enhancing soil structure and nutrient content,鈥� she explains. 鈥淭his would not only improve farm sustainability but also create added value for waste fibers from the alpaca.鈥�
Experimenting with varying quantities of the three materials to come up with the best possible combination that will yield fast acting compost.
Augustine Kwame Osei is a post-doctoral fellow in the Faculty of Environment conducting the experiments with Dr. Maren Oelbermann.
The research group is now conducting a first-of-its-kind experiment combining alpaca waste fiber and manure with biochar; a carbon-capture product that is a charcoal-like substance. It鈥檚 a soil supercharger enhancing the health of soil while also playing a role in long-term carbon storage. In the lab, the team is experimenting with varying quantities of the three materials to come up with the best possible combination that will yield fast acting compost.
鈥淲hat鈥檚 exciting about this project is that we are using a waste problem to tackle a soil problem,鈥� says Augustine Kwame Osei, post-doctoral fellow in the Faculty of Environment. 鈥淭he icing on the cake is it鈥檚 all locally sourced.鈥�
While Stewart supplies the alpaca waste fiber and manure, the researchers are relying on for the final core ingredient. The industry partner is a premiere biochar market brand, and the only Ontario-made commercial scale manufacturer of certified organic, premium quality biochar.
Forming diverse new partnerships like this one is a hallmark of the Faculty of Environment鈥檚 new strategic plan, Environment 2035, which champions collaborative research with industry and community partners. It鈥檚 an approach that is propelling boundary-breaking research and is just one of the many reasons 蓝莓视频 is a leader in sustainability research and education.
By spring the researchers hope to identify the three most productive combinations to test out on the farm and then analyze the impact they have on the soil in the following fall. The potential success of such a product would extend beyond Maple Ridge Acres and address critical environmental challenges.
鈥淭his is a first step to tackling a bigger problem in terms of improving waste management to produce products that can be used by farmers to grow better crops and reduce agriculture鈥檚 footprint in terms of climate change,鈥� Osei says.
