Carbon Cycle



In a nutshell
Carbon Cycle is a biochar producer from Bavaria that is also part of Microsoft’s Carbon Removal Scheme. The biochar is produced from wood chips originating from sustainably managed PEFC-certified forests. A businessman, the developer of the carbonization system, two public service employees, and a medical professional from the pharmaceutical industry make up this company’s unlikely team. The enterprise’s objective is to provide solutions for modern agriculture through its high-quality biochar products. The application of biochar on the land protects groundwater and biodiversity by reducing nitrate leaching and the use of fertilizers while improving the nutrient retention of the soil. In parallel, the CO2 captured in the biochar production is stored in the ground for centuries.

Co-benefits
In addition to reducing CO2 from the atmosphere, the project generates extra benefits for the communities and the environment.








Our partner Carbon Cycle uses wood chips from PEFC certified local forestry to produce biochar. The CO2 is initially captured during the growth of the tree. Maintaining the forest creates biological waste with low economic value that would else be combusted or left to decompose. Instead, Carbon Cycle transforms the waste in the form of wood chips into biochar, thus, safely capturing CO2 that would otherwise be released. Said biochar is the result of a process named pyrolysis, closer explained in the methods section. Through pyrolysis, the carbon inside the timber waste is brought into a stable form and can consequently be stored in the ground for centuries.

Carbon Cycle’s biochar production is certified with the European Biochar Certificate (EBC).
The use of modern agricultural methods has caused various problems in local ecosystems. One example with far-reaching consequences is the excessive manuring of fields and meadows. It leads to increased nitrate concentrations in groundwater, lakes, and streams, as well as a decline in the biodiversity of meadows, nearby forests, and moors. These developments ultimately result in reduced drinking water quality and contribute to the decline of biodiversity in fauna and flora.
This is precisely where Carbon Cycle comes in with its Biochar products. The use of biochar reduces nitrate leaching and nutrient losses from the soil. Due to its vast surface area and porous structure, biochar is ideal for absorbing nutrients and nitrates and preventing their leaching. This significantly reduces the use of fertilizers, protects groundwater, and sustainably improves soil fertility. In Carbon Cycle’s products, the biochar is added in a first step either to the feed, the slurry, or the stable bedding. This improves animal health, animal welfare, and the stable climate and charges the charcoal with nutrients. The biochar thus becomes a valuable natural fertilizer when applied.
These impressive benefits are achieved by the biochar while at the same time sequestering CO2 in the soil for centuries.
Finally, Carbon Cycle’s biochar production is certified with the European Biochar Certificate (EBC) from the independent international Ithaka Institute. The guaranteed permanence of the carbon stored in the soil is >1000 years. As part of the certification, the CO2 removal potential of the biochar is quantified using life cycle analysis done by Norwegian LCA provider Accend. The analysis also includes the subtraction of any CO2-Emissions occurring during production. Subsequently, the traceability from production to the place of application and final storage in the soil, as well as the total amount of CO2 permanently removed, is certified by Puro.Earth. Moreover, Carbon Cycle’s biochar is certified for use in animal food, according to GMP+. Biochar mixed into animal food has a positive effect on animal health and even reduces the methane emissions from cows.
Our project contacts are Dr. Rudolf Zeitler from Carbon Cycle and Paul Ferguson from Accend. Carbon Cycle has appointed Accend to carry out the certification process and organize distribution. Accordingly, Paul Ferguson is our primary contact person for the project. Paul is a very communicative person and does not hesitate to go the extra mile to satisfy his customers. We are looking forward to continuing to work with Paul and Carbon Cycle.

Husk
In a nutshell
Husk is a social enterprise producing biochar products from organic rice husks in Cambodia. Producing biochar is an ancient practice believed to have originated in the Amazon thousands of years ago. The company works together with local rice farmers to revive this practice and transforms their biowaste into valuable biochar. With the help of Swiss technology, the CO2 capture by the rice plants gets trapped inside of the produced biochar. The biochar, consequently, used as a fertilizer then stores the CO2 permanently in the soil.

Our partner Husk uses rice husks – a waste product – to produce biochar. The CO2 is initially captured as the rice grows. After the rice harvest, instead of being thrown away or burned the rice husks – which contain carbon- are pyrolyzed (burned without oxygen) to produce biochar. Husk does this using machines from the Swiss technology developer Ökozentrum. The carbon is thereby turned into a stable form sequestering it for long-term and avoiding it’s release back into the atmosphere. The biochar is used as an effective biological fertilizer and is applied to agricultural fields by many local farmers. This stores the CO2 in the soil and also helps improve the soil quality which can even improve the next harvests.

Cambodia’s economy relies largely on agriculture with rice being its main agricultural product. Our project partner Husk uses biological waste from the rice production to sustainably boost agricultural production while capturing CO2.
Like in many other developing countries farmers in Cambodia face critical challenges, such as nutrient depleted soils and low resilience of their crops to pests and disease. Husk helps local smallholder farmers overcome those challenges with the help of their fair-priced organic fertilizers and pesticides.
Husk uses rice husks from organic farmers to produce biochar. Through their setup directly at organic rice mills they have direct access to the abundant resource. Consequently, the affordability of their products for smallholder farmers is ensured by low raw material and logistics costs combined with cross financing from the income generated by Carbon Credits. Husk’s product range includes largely unprocessed organic biochar to restore degraded soils, natural insect repellent as a biological pesticide alternative and carbon-based fertilizer to increase soil fertility and nutrition levels. The products can be applied in a wide range of vegetable and grain production.
Their research in collaboration with USAID has shown that their products contributed to an increase of crop yields by 29% on average. This directly increases farmer revenues while reducing chemical usage and soil degradation. At the same time, farmers applying the products are participating in the fight against global warming by storing CO2 permanently in the soil.
Our project contact is Husk Co-Founder Carol Ruis. We have experienced Carol as a very energetic person with an internal fire burning for social entrepreneurship. Her co-genial partner Heloise Buckland is an extremely experienced social entrepreneur who dedicated herself to the fight against climate change. Carol herself, on the other hand, has extensive experience in Business Development in particular in the South East Asian market. When piling up the experience of the whole Husk team you get a construction higher than the prime tower in Zürich, the Berliner Fernsehturm or any other building around here. This makes us feel very optimistic about the future development of this project. As a salesperson Carol is naturally convinced by her product, but one can tell that it goes beyond that. Carol and this inspiring project just seem like a perfect fit, leaving us excited to continue our partnership with them.
