Highline Mushrooms continues to be a leader in sustainable mushroom farming.

Our focus on ethical, sustainable and renewable growing practices is a top priority, and we rise to the challenge of creating a clean and sustainable future for our environment, our farms, our associates, our community and our customers.

Farming Practices

Mushrooms Growing

Nature’s Recyclers

At Highline, we use technology to convert agricultural by-products into a nutrient-rich substrate for mushrooms to grow. Taking what other agricultural sectors might consider waste – straw, stable bedding, spent grain – and input into our substrate process. Our nitrogen-rich spent mushroom substrate (SMS) is shared with the community as soil amendment at the end of production.

Water Recycling

At Highline, we recognize the need for water conservation. We have optimized the growing process by reducing evaporation in our growing rooms, reusing process water in our composting operations, and utilizing greywater to reduce further the need to use groundwater.

We are able to produce one pound of fresh mushrooms using about 6 litres of water, a fraction of what other foods require.

Energy Management

Through the use and installation of state-of-the-art growing technology, we have been able to reduce our energy demand. By using modern and quality materials in the construction of our farms, we are able to maximize the energy we do use all while minimizing our impact on the environment.

Small Farm Footprint

We can grow millions of kilograms of mushrooms on a one-acre farm. Our unique indoor vertical growing facilities have a smaller footprint than other crops, allowing Highline Mushrooms to grow over 5 pounds of fresh mushrooms per square foot.
