Raumgarten makes the difference – live more sustainably!

How can I live more sustainably?

You’re not the only one asking that! We have a solution: Use our Raumgarten!

To start the comparison: Conventional vegetable farming, using lettuce as an example, significantly contributes to greenhouse gas emissions. On average, growing one head of lettuce produces around 120 g of CO₂ equivalents. This emission comes from several sources: fertilizer use is particularly significant, with the production of one kilogram of fertilizer causing approximately 1.6 kg of CO₂. Additionally, operating machinery for cultivation, maintenance, and harvest causes further emissions—about 10 to 20 g of CO₂ per plant. Another major factor is transportation from farms to retail stores. For a 100 km truck journey, approximately 30 g of CO₂ is emitted per lettuce head (based on an average weight of 300 g).

In contrast, the Raumgarten offers a much more eco-friendly alternative. Seed production is significantly more efficient, with lettuce seed production emitting about 0.1 kg of CO₂ equivalents per kilogram of seed. Only 0.1 g of seed is needed for one head of lettuce, resulting in just about 0.01 g of CO₂ for transport to a nursery (assuming 100 km distance). These emissions are negligible compared to conventional production.

Another important factor is energy consumption in the Raumgarten. Lighting and climate control require about 40 kWh of electricity per month for 48 plants, which equals roughly 0.833 kWh per plant. The CO₂ emissions from this energy use vary by energy source. Using biogas, considered CO₂-neutral, results in no additional emissions. If solar energy is used—with an average emission of 50 g CO₂ per kWh—the total emission per plant is around 42 g of CO₂.

In summary, using solar energy, the Raumgarten produces a maximum of 42 g CO₂ per head of lettuce, making it significantly more sustainable than conventional cultivation, which produces around 120 g CO₂ per plant. Additionally, the Raumgarten eliminates long transport routes, further reducing emissions. These figures highlight the Raumgarten's potential to significantly reduce CO₂ emissions and offer a sustainable solution for growing vegetables.
