Note that all required fields must be filled. Go to the menu at the bottom "How" and tap "Buyer me". Here is a detailed description of how you can create a buyer and contact information for Biomass Auctions.

No, you often cannot. Biomass Auctions tries to describe the delivery and contract conditions in as much detail as possible in text and images. If something is not adequately described, you can ask questions in the "question and answer" tab during each auction. All questions will be answered and published there so that everyone bids on the same basis. In any case, inquiries must always go through Biomass Auctions.


After your registration, you will receive an email with the status. It will take about 1 business day before the CVR approval can be completed by Biomass Auctions’ staff. You will receive an email as soon as your account is approved and activated. Before that, Biomass Auctions may contact you if we have any questions about your certification level.

Note! If you do not receive our emails, please check your unwanted email/spam filter, or contact us at


If you have recently registered an account, it must first be approved before activation. If you registered several business days ago, a blocking of the account might be due to a breach of the terms and conditions or that we have incorrect contact information on you. Send an email to immediately to clarify this.


No, any bid is legally binding. Read the detailed terms in the terms section.


As a starting point, any dispute is a matter between the buyer and the seller and must be settled between the parties.

If no agreement can be reached, please contact Biomass Auctions by email:

You will be contacted shortly afterwards for further questions. Biomass Auctions does not become a party to any dispute between the buyer and the seller, and any claims in this regard cannot be directed at Biomass Auctions. However, we are happy to help resolve the matter. Read detailed terms of purchase in the terms and conditions section.

Yes, in principle, you can.

But it is also easy to limit the number of hauliers. In the description of each auction, for example, it may be stated that the seller may use only "hauliers who conduct driving of wood chips/straw as their main activity", or it may be a requirement that only one or more named hauliers may deliver. It is also possible to require certain to nationality, language, types of trucks, etc.

The flexibility of the Biomass Auctions platform ensures that all options are open.

The buyer in consultation with Biomass Auctions determines the maximum price.


Biomass Auctions screens the heating plant and fills out the description and specification for each auction. We try to give an accurate description of the object to the best of our ability, with the aim that everyone should be able to bid on a correct and informed basis. If the buyer finds conditions that are not properly covered, questions can be asked in the tab "questions and answers". Questions asked at least 24 hours before the end of the auction will be answered. Anonymised questions and answers will be published on the site.


The buyer is always responsible for the correct description. The description will be approved by the buyer before the auction is published.


The minimum bid reduction is dependent on the product and the sales unit and usually follows the following rules:

  • Wood chips are traded in DKK/GJ, and the minimum bid reduction is DKK 0.10
  • Straw is traded in DKK/tonnes, and the minimum bid reduction is DKK 1.00 (0.1 øre/kg)
  • Garden/Park chips/Roots for waste burns are traded in DKK/tonnes, and the bid reduction is DKK 1.00

On each auction, you can see the minimum bid reduction.

Another bidder has used the auto bid feature. Auto bid follows the same bid lowering rulebook as regular bids and counterbids until the lower limit is met. When this happens, an e-mail is sent informing the bidder that her/his auto bid has now been underbid by another bidder. All bidders can use the auto bid feature.

Auto bids are indicated with an (A)


This is how auto bids works:

In the example below, the buyer has set a maximum price of 42 DKK/GJ, and the next bid option is 44.30 DKK/GJ. The bid reduction is 0.10 DKK (Note that the bid reduction may be different in the individual auction)

  1. If you try to place an auto bid of DKK 43.00 (which is still above the buyer's maximum price) this bid will not be accepted. If you continue, the bid will be considered a regular bid and immediately go from the starting point to 43.00. Auto bid only works if you bid below the buyer's maximum price.
  2. If you place an auto bid of DKK 41.00, the bid will shortly move from the starting point to the maximum price of DKK 42.00/GJ. After that, the price will drop (when others bid) on the object with the "bid lowering" down to DKK 41.00.
  3. If another bidder had previously placed an auto bid on exactly the same amount, the first bidder will win the auction if the auto bid is the lowest at the end of the auction.
  4. If an auto bid is undercut, an email will be received with this information.
  5. Note: You can place a new auto bid even if the first auto bid is not outbid by another bidder. The new auto bid replaces the first auto bid (there is only one "active" bid per user)

A security rule is built-in to protect against some error entries. If you lower the price by more than 10%, the system will ask you to confirm your bid before it is submitted.

What you experience is, as in other auctions, a competition just before the gavel falls. The system is designed so that a new winning bid prolongs the auction by another 10 minutes so that everyone can bid. The auction ends only when the lowest bid is not changed for 10 minutes.


The buyer's fees differ from product to product. In some cases, it is a percentage of the price, and in other cases, it is a fixed price per unit of sale. The fee is deducted from the settlement base from the heating plant. The settlement price (price after the fee is deducted from the bid price) is shown when you bid.


Yes, you can.

In some cases, certification is not required by the heating plant. For example, it may be small heating plants (not covered by the industry agreement on sustainable biomass) or industrial companies may use the chips for process heat. These are not subject to the industry agreement. Each auction will make it clear which requirements apply.

There may be cases where an auction is published, but bidding is blocked. This may be partly due, for example, to the fact that the buyer, typically in connection with larger purchases, wants it to be settled on tender-like terms. Here you typically have a period of 2 weeks during which questions can be submitted and will be answered. These questions and related answers will be published in anonymised form under the "questions and answers" tab and may result in changes to the auction description/contract. Only then will bidding be opened, so that everyone bids on even terms.

Another example may be a heating plant that wishes to offer its main quantity to, for example, 3 different suppliers to secure supply. Here, the auction will be held as 3 separate auctions that do not run simultaneously. When the first auction is completed, the winning party will be prohibited from bidding on the next 2 auctions. After that, auction number 2 runs, and the winning party is banned from bidding on the last auction.

In both of the above cases, the description will clearly describe how the auctions will proceed.

No, it is also possible to shop for delivery at an external storage facility if the heating plant wants to establish an emergency warehouse - either itself - or together with other heating plants.

It is also obvious to use Biomass Auctions for plants that can only receive biomass by ship. If Danish-manufactured wood chips is a priority, it is possible to make targeted purchases where the biomass is delivered at a Danish port and then sailed to the port of the plant. If more suppliers are wanted, Biomass Auctions can facilitate sampling of the delivered loads.
