The forest, the forest residues and the climate.

April 17, 2025

The forest must be an all-rounder - today and even more so in the future: it provides the renewable raw material wood, stores CO2, ensures biodiversity, protects settlements from natural hazards and is an important recreational area and workplace. Our Reversepowerplants use forest residues in the form of forest chips for sustainable energy generation and the production of valuable green carbon. But what does sustainable forest management have to do with it? Why is the regular cycle of harvesting and replanting trees so important for our environment and energy production? And what do we actually mean by sustainable forest management?

Forest: The all-rounder in (climate) change

The forest must be an all-rounder - today and even more so in the future: it provides the renewable raw material wood, storesCO2, ensures biodiversity, protects settlements from natural hazards and is an important recreational area and workplace. Here in Austria in particular, the potential of forests is huge when you consider that, at 48 percent, forests cover around half of Austria's surface area. But just because something is obviously there doesn't mean that we deal with it sufficiently. Can we still see the wood for the trees? With all its needs and opportunities? And what does the forest have to do with our reverse power plants?

Forest as a climate protector and energy source

The forest is not only a place of recreation and home to numerous animal and plant species, but also plays a crucial role in the fight against climate change. However, as trees can grow very old, forests are slow to adapt to climate change. The forestry industry is therefore looking for ways to manage forests so that we can still use them in the next century. And because trees also absorb the most carbon dioxide (CO2) from the air through their leaves during the growth phase, forest management is becoming increasingly important.

Conversely, this means that regular harvesting and replanting is part of climate protection and climate change. And what does this have to do with us and our reverse power plants? Quite simply: the harvesting process always produces residues - and we use these forest residues in the SYNCFAFT reverse power plants to produce resource-saving electricity, heat, Green Gas and green carbon.

The CO₂ cycle in the forest: young trees as efficient climate protectors

A common misconception is that old forests are the largest CO₂ reservoirs and should therefore remain untouched. In fact, the situation is more complex:

💡Young, growing trees absorb significantly more CO₂ than old trees. During the growth phase - around the first 20-40 years of their life - trees store carbon particularly intensively, as this is when they grow fastest and build up biomass.

This can be illustrated with a simple picture:

  • A young tree is in its "growth phase" and needs large amounts of carbon, which it absorbs from the atmosphere in the form of CO₂
  • With increasing age, this growth slows down, and with it the absorption of CO₂
  • An old tree stores more carbon than a young one, but absorbs comparatively less new CO₂

Regular harvesting and replanting:

Sustainable forestry utilizes this natural process by:

  1. Harvesting mature trees: Trees are harvested before they enter the slow growth phase
  2. Planting new trees: these young trees actively absorb CO₂ from the atmosphere
  3. The harvested wood is used in the long term: Long-term use means that the stored carbon remains sequestered

This principle of sustainability was introduced in forestry over 300 years ago - never taking more wood than can grow back. Today, we know that this practice not only secures the supply of wood, but also actively protects the climate - a principle to which SYNCRAFT has been committed since its foundation.


"Forests are effective climate protectors, but at the same time they also suffer from climate change. Forest Day is a good opportunity to draw attention to the fact that sustainable forest management is indispensable in two respects: on the one hand, it increases the climate protection effect of forests because it makes wood available that, when used as a material and building material, extends the carbon reservoir from the forest and replacesCO2-generating materials. On the other hand, sustainable management and active forestry are needed right now to help forests adapt to climate change."

Richard Stralz, Chairman of proHolz Austria, the Austrian forestry and timber industry association


💡Important fact: The global annual wood harvest is around 3.9 billion cubic meters, or around 2 gigatons - which is similar to the amount of steel consumed worldwide! This enormous quantity underlines the importance of wood as a sustainable raw material.

forest residues: the driving force behind Reversepowerplants

As already mentioned, wood harvesting inevitably produces residues. In the past, some of this forest residues was left in the forest, where it rotted and released the stored CO₂. And this is where our Reversepowerplants come into play: they use the forest residues in the form of wood chips to generate renewable energy and produce green carbon.

Our woodchippings are not to be confused with white woodchippings, which are already widely used and reused. Our wood chips are unprocessed and are used as fuel in the Reversepowerplant together with bark and small impurities. The impurities are filtered and separated in the Reversepowerplant so that only the useful residual wood remains.

The patented SYNCRAFT technology makes it possible to use precisely this material in the form of forest chips as an efficient fuel in our reverse power plants.

Principles of sustainable forest management

Our Reversepowerplants use forest residues in the form of forest chips as a valuable resource. But where does this material come from? For us, responsible forest management is a central component of our climate-positive philosophy. Only if forests are managed sustainably can they fulfill their important role as a CO₂ reservoir and source of renewable resources in the long term - the principles of sustainable forest management include

  • 🌳 Selective harvesting
    Not all trees are felled at the same time - instead, mature trees are selectively removed to keep the forest ecosystem stable.

  • 🌱 Immediate reforestation
    Immediately after the timber harvest, new trees are planted to maintain the natural forest cycle.

  • 🌿 Promoting biodiversity
    Instead of monocultures, we focus on species-rich mixed forests - for more biodiversity, ecological resilience and healthy forests.

  • 🛡️ Soil protection
    Gentle harvesting methods prevent soil erosion and preserve the structure and fertility of the forest soil.

  • 📜 Certified forest management
    Compliance with recognized standards such as
    FSC or PEFC, which ensure ecological, economic and social criteria.

A sustainable (reverse) cycle for the future

SYNCRAFT Reversepowerplants are specially designed to make the most efficient use of forest residues - a perfect link between sustainable forestry and climate-neutral energy generation.

The sustainable use of our forests in conjunction with the reverse power plants is a perfect example of a functioning circular economy. By regularly harvesting trees in their optimal growth phase and consistently reforesting them, we create a continuous cycle of CO₂ sequestration. At the same time, we obtain a renewable raw material and energy source.

Green Carbon in metallurgy

Metallurgy is facing a historic transformation: while the steel industry is responsible for 5-7 percent of global greenhouse gas emissions, Green Carbon offers a revolutionary alternative to fossil coals. With its reverse power plants, SYNCRAFT shows how regional forest residues can be turned into sustainable carbon for the defossilization of the metal industry.

Building materials with green carbon: the future of construction

Conventional building materials are responsible for around 11% of global CO₂ emissions. To change this, we need innovative, new building materials - which not only save CO₂ emissions, but also bind CO₂ in the long term. And thus become a CO₂ sink. This is made possible by building materials that contain green carbon, for example.

Certificates for climate protection

From A for application to Z for certification: REACH registration, European Biochar Certificate, C-Sink certificates - confirmed quality against climate change? We were one of the first system manufacturers to be recognized as an "Endorsed System Provider" by Carbon Standards International (CSI) in 2024. But what does this mean in concrete terms, which certifications are important and why are they so essential in our industry?
