With BOXofGREEN, you gain a number of advantages compared to traditional tree planting.
Benefits that support trees, biodiversity, landscapes — and your budget.
✅ Easier planting of new trees.
✅ Fewer work processes during planting/installation.
✅ Fewer gardener visits for tree maintenance.
✅ Reduced use of artificial irrigation.
✅ Less driving = more environmentally friendly.
✅ Increased use of natural rainfall = reduces pressure on sewer systems during cloudbursts.
✅ No visible water tanks.
✅ Greater growth security.
✅ Faster growth rates.
✅ Strong root activity in the stone wool = shorter staking period.
✅ Ensures better root establishment in urban soil, where space for topsoil is limited.
✅ 5-Year Growth Guarantee.
To plant the tree correctly, start by digging a square hole large enough to fit the BOXofGREEN box.
Place the entire box, including the hessian sack, into the hole and fill the inside edges with topsoil while filling the outside with sand or soil.
Position the tree in the center of the hole and continue filling with topsoil inside and sand or soil outside.
Firm the soil thoroughly to ensure stability.
Secure the tree with 2–3 supporting posts placed inside the BOXofGREEN box. (If the soil is very clayey, it is recommended to build a macadam base underneath the batts.)
Finish by adding 300–400 liters of water. Job done!
BOXofGREEN’s stone wool is made from natural basalt rock. The stone wool has a porosity of approximately 97%, meaning that production requires a relatively limited amount of raw materials.
Basalt – A Natural Material
BOXofGREEN’s stone wool is primarily made from basalt – a natural volcanic rock that is formed and renewed through the Earth’s geological activity. Every year, the Earth produces 38,000 times more volcanic rock than is used in the production of stone wool. Our partner, Lapinus/ROCKWOOL, sources basalt from areas including the Eifel region in Germany. The raw material is processed into stone wool at ROCKWOOL’s facilities, including their plant in Hobro, Denmark. The stone wool consists of approximately 97.5% basalt rock, around 2.4% resin binder, and less than 1% water management additive (by total weight).
Circularity: Nearly 50% Recycled Material
In addition to basalt, recycled stone wool products are an important part of the raw materials used in BOXofGREEN. Stone wool can be recycled infinitely without any loss in quality. Through ROCKWOOL’s recycling program, Rockcycle©, used stone wool is collected and reused in new products.
This helps reduce the consumption of new resources and minimizes waste. Additionally, ROCKWOOL uses leftover materials from other sectors in its production, further strengthening the circular value chain.
By choosing BOXofGREEN, you are promoting a circular economy, reducing waste, and supporting the UN Sustainable Development Goals – particularly Goal 12 on responsible consumption and production.
Transparency and Responsibility
ROCKWOOL actively works on transparency and sustainability. According to the company’s 2022 Sustainability Report:
• ROCKWOOL ranked 16th on the list of the world’s most sustainable companies and 1st in the building products category (Corporate Knights Global 100).
• In 2022, ROCKWOOL reduced the CO2 intensity of its products by 17% compared to 2015.
Safe for the Soil
BOXofGREEN’s stone wool is safe to use underground and causes no soil pollution. The material complies with the Dutch soil quality standards (BBK), which are administered by Bodem+ Rijkswaterstaat, the Ministry of Infrastructure and Water Management in the Netherlands.
Hessian
For certain parts of the product, we use hessian made from jute – a plant fiber that is 100% biodegradable.
BOXofGREEN’s climate footprint (GWP) varies across the different phases of the stone wool's lifecycle, from production and consumption to waste management. Here is an overview of the total greenhouse gas emissions and climate impact (GWP) across the various phases of our products' lifecycle. Please contact us if you would like a more detailed breakdown of the figures.
GWP stands for Global Warming Potential and is measured in kilograms of CO₂ equivalents (kg CO₂e), covering a wide range of gases, including CO₂. GWP Total is a summary of emissions from phases A1–C4. The climate footprint is documented in our third-party verified Environmental Product Declarations (EPDs).
