Latvian eco-greenhouse uses stone wool substrates and landfill gas energy

A unique eco-greenhouse has been set up on the largest solid waste landfill in the Baltic region.

Getliņi EKO is unique in many ways. First, it is heated by thermal energy produced by waste-to-energy method. Electricity is generated in the process of burning the gas emitted by biodegradable garbage, part of which goes to the greenhouse needs, and the rest to the Latvenergo electric power system.

Ecological greenhouse covers an area of 11,412 square meters, on which about 25,000 plants grow. Cucumbers, tomatoes and flowers are grown on agronomic basalt substrate. About 500 tons of tomatoes and the same amount of cucumbers are produced per year.

Stone wool substrate allows taking full advantage of water and energy, planning carefully plants nutrition specifically at each stage of growing, while monitoring quality of the product which consumers receive.

Moreover, stone wool agro-substrates are eco-friendly and fully recyclable, which is especially important in the context of modern challenges to reduce the impact on environment.

Recently, both companies unveiled their products and solutions at GreenTech 2019, the international horticulture industry trade-show.
