1. Scope of application
The website Waste-to-Energy Research Technology Germany - WtERT ( provides its services based on the terms of use stated here forth. The Terms of Use provided online at the time of using the services of this site shall be applicable. We shall not accept provisions in derogation of these terms unless they have been confirmed by the Operator of this Site in writing. By using this website you explicitly signify your agreement to these Terms of Use and without requiring further explanation.

2. Content/Offers, Disclaimer
WtERT provides own and third-party information and knowledge products. Any product proceeding from a partner company is labelled accordingly. In the event of loss or damages, incurred because you relied on information or content, which you received whilst using WtERT, the Operator shall only be liable, if the damage was caused intentionally or with gross negligence by any legal representative or vicarious agent of WtERT or if, due to slight negligence, an obligation is violated that is essential to the contract (contractual obligation). For information offers and knowledge products of partner companies and private persons (e.g. in discussion forums), WtERT provides solely the technical medium. Such information as provided by third parties is information pertaining to the respective originators, authors or disseminators and does not pertain to WtERT. WtERT shall therefore and under no circumstances be liable for the accuracy or reliability of this content, information or offer. In particular, WtERT shall not be liable for any losses or damages incurred to the user who has relied on such information. Contributions, which could damage third parties or which contain information purely for advertising purposes shall be deleted by the webmaster. Any infringement of criminal or competitive law shall be prosecuted immediately. The Operator dissociates himself explicitly from such contributions. The insertion of hyperlinks in our offer is merely to provide access pursuant to Article 3, paragraph 3 of the German Tele-Services Act (TDG). We are not to any extent responsible for the content of linked websites.

3. Proprietary Rights, Use of Content
Proprietary, copyrights and other rights of third parties accessed via WtERT remain wholly pertinent to the holder of these rights and are protected accordingly. Unless stated otherwise in an individual agreement, you are granted to make some limited copies of portions of the Site Content provided that these copies are solely for your personal use and that you keep all copyright or other proprietary notices intact. The distribution in any form of the content and data obtained from the WtERT Site and uploading Site Content on any third-party website is strictly prohibited. It is strictly prohibited to use the WtERT databases for commercial purposes. Any violation thereof shall be legally prosecuted. An online subscription entitles you to the use of the database exclusively during the agreed period, and extends to you individually and to one computer. For use by more than one user or on more than one computer, there are subscription packages for a pre-determined maximum number of users and computers. There are special conditions and offers for companies. In closed user groups, each user receives a personal user name and password for his workplace with which to access the Site. The user agrees to maintain this information as confidential and not to pass it on to third parties. The user shall change this login information should it for any reason have become known to third parties. Passing on database content to third parties, even in part, is strictly prohibited.

4. Agreement on Goods and Services
Goods of our content partners are delivered upon purchase to the postal address provided to us. The shipping costs are calculated separately and at the customary rates. The place of performance is the publisher’s distributing warehouse. As a rule you carry the costs for delivery and as the case may be for additional taxes or customs duties. In as far as goods or services of third parties are offered on the WtERT Site, any agreement made is exclusively between you and the said third-party provider. Any claims are to be directed to the aforementioned third party. All offers are subject to the respective pricelist and delivery conditions of the provider valid at the time of purchase.

5. Advice of Withdrawal

(1) Right of withdrawal As a Customer, you are entitled to revoke your contractual statement in writing (e.g. letter, fax, and email) within 14 days without stating reasons, or, if you have already received the goods, upon sending them back within the time period stated above. The deadline begins no sooner than the receipt of the written advice about the right of withdrawal but not before the receipt of the goods by the Customer (with partial deliveries of the same goods not before the receipt of the first part of the delivery) and not before fulfilling our information duties pursuant to Article 312c, paragraph 2 of the German Civil Code (BGB) in connection with Article 1, paragraph 1, 2 and 4 BGB InfoV as well as our obligations under Article 312e paragraph 1 clause 1 BGB in connection with Article 3 BGB InfoV. In order to not exceed the withdrawal period, the revocation shall be posted in due time.
(2) The withdrawal must be sent to:
WtERT Germany GmbH
Lipowskystr. 8
81373 Munich, Germany
(3) Consequences of Withdrawal
In the case of an effective withdrawal, mutually received goods and services and as the case may be emoluments (e.g. interest) must be returned. Should the User be unable to return the goods/services completely or only in part or only in a deteriorated form, he/she must pay compensation. This does not apply in the case of goods, if the deterioration of the goods is exclusively attributable to the inspection that would have been possible in a retail shop. No indemnification is due, if the deterioration is such as stated in these Terms of Use. Packable goods are to be returned at our risk. You bear the costs of returning the goods, if the delivered goods are the ones ordered and if the order value does not exceed €40.00 or if the value exceeds this amount and you have at the time of withdrawal not yet made a payment or a partial payment pursuant to this agreement. In all other cases, the goods can be returned free of charge. Non-packable items are collected from the customer. Obligations for refund of payments are to be fulfilled within 30 days. This period begins for you with the communication of withdrawal or the return shipment of goods, for us with the arrival of said goods.

6. Terms of Use – Posts and Forums
By using the dialogue facilities (e.g. discussion forums) on WtERT you agree to restrict yourself to exchanging opinions on a professional level, to refrain from advertising and to respect the interests of others.

Public and Communication

Priciples concerning the public
When we are presenting the professional articles of our content partners, we try to refer to the authors irrespective of the actual copyright. Regarding this as a common interest, we also check and update the autor data we receive from our content partners and change them, if we obtain newer data.
In that we see a very high advantage for our users as well as for the authors themselves, because it is just this data- and information build-up that helps us developing our WtERT expert-database.

Authors can disagree with this principle by sending a mail to and will then be removed from the expert-search-function. However they will stay in the database insofar they are listed as autors of a content partner. Possibilities to contact them will be disabled.

Communication inside the community

We regard it as common interest of the WtERT Community to provide users with the possibility to contact authors and experts respectively. Communication will take place on the personal pages of the author on the WtERT plattform itself to ensure not to pass on any e-mail-adresses. If someone contacts an autor or expert, the recipient will receive a standarsized message "Post im Profil". After login the author/expert can handle this message on his personal page. In this way experts from science and experience that are very busy can delegate this process without having to give employees an access to the personal e-mail-account.

The e-mail-adress will be used for this message. It will as well be used to send newsletters or auhor notification (concerning important changes) and author documents (concerning new articles). All of these services can be controlled, ordered, cancelled or countermanded by the author at any time. For a start this will be possible through sending a demand to the operating company (send an e-mail to

In the medium term authors/experts will be able to choose the depth and the amount of communication themselves.
