  • World energy dramatic consumption increase…


  • …that cause serious consequences.


  • How can we reduce the energy consumption ?


  • Right approach : China Saving Energy Stiffer Law 严格 法律


    • Standing Committee of China's National People's Congress (NPC), the country's top legislature, has voted to adopt revisions to the Environmental Protection Law, enshrining environmental protection as the government's overriding priority, with specific articles and provisions on smog.
    • For the first time, the law has established clear requirements for ecological protection.

  • One solution : Saving Energy in Building 大楼 节约能源


    • In a typical European household, well over half the money spent on fuel bills goes towards providing heating and hot water, so it makes sense to invest in the most energy-efficient heating system.
    • So the main sector of energy savings is found in the housing communities.

  • Concrete example : Housing Saving Energy (Tianjin 天津)


    • Location : Bīnhǎi Xīn Qū (滨海新区)
    • Building, 40 floors, 30 000 m2
    • Concern Equipment : Heating or Air Conditioning
    • Estimated investment cost : $ 10,000
    • Return on investment : 13 months
    • Estimated 3 years Energy savings : $ 50,000
    • White certificate earning : $ 3,500

  • Example : Boilers Saving Energy China Potential Market


    Considering surface of more than 5000 m2 :
    • 12 millions of device today in activity has to be checked.
    • 25 % has to be replaced.
    • 75 % has to be rejuvenated through a saving energy device.
    • China boilers with saving energy device implementation market is estimated to a level of 24 billions of yuans (2,3 Md US$).

  • Chaoyang Saving Energy Plan 節能 计划朝阳区 節能 计划


    What could be for the 5 years to come a plan to slash the energy consumption and to reduce the CO2 emission in the Cháoyáng Qū ?
    A triple project target
    • A reduction of the pollution and the emission of CO2
    • Inhabitants of buildings will save money on their energy bill
    • The Municipality will get to a new source of income

  • Chaoyang Estimates Saving Energy Plan

  • Saving Energy means Saving Money for your properties ! 节省


    How to save money and add value to your real estate through an ecological way ?
    5 five ways to do it !
    In Europe :
    (1) For the housing building equipped with saving energy devices, the market rental values, yields and acquisition prices have steadily increased :
    • 2011 : + 3 %
    • 2012 : + 2,7 %
    • 2013 : + 2,6 %
    (2) Those ones that haven’t such equipment have experienced a sharp decrease that intensified over the years :
    • 2011 : - 2 %
    • 2012 : - 2,6 %
    • 2013 : - 4,7 %

  • Europe Saving Energy Plan


    (1) In Europe, residential building consumption represents 45 % of the total energy cost (2013).
    This is the main sector of energy savings.
    (2) Under the Renewable Energy Directive 2012/0288 (COD), the EU aims to get 20% of its energy from renewable sources by 2020.

  • Carbon Trading : The White Certificate


    • A white certificate, also referred to as an Energy Savings Certificate (ESC), is an instrument issued by an authorized body guaranteeing that a specified amount of energy savings has been achieved.
    • The white certificates are given to the producers whenever an amount of energy is saved whereupon the producer can use the certificate for their own target compliance or can be sold to (other) parties who cannot meet their targets.
    • Each certificate is a unique and traceable commodity carrying a property right over a certain amount of additional energy savings and guaranteeing that the benefit of these savings has not been accounted for elsewhere.

Decontamination of water’s installation




Founded in 1816, Tevan Bv[1] is a European leading manufacturer in the areas of cleaning and decontamination products through innovative applications mainly in the treatment of water’s installation.

The main today activities : drinkable water systems & installations & global decontamination.

Tevan has developed efficacious, quick and environmentally friendly solutions addressing infection and contamination problems responsible for disastrous calamities. Based on key competitive assets (patent, certifications, R&D projects), Tevan formulations applications are widely bound to the European Homologations.

Targeting surface or volume treatment, they apply to a wide variety of sectors :

Water treatment, Agriculture, Aquaculture, Food industry, Medical sector, Nursing homes, Sanitary fields and others.




In recent decades, Tevan has gained increasing worldwide recognition and become a focus of international cooperation in decontamination in water’s installation, playing a leading role.

The results of these ecological and innovative formulations have been confirmed by several international organizations :


These formulations are already homologated in some key countries (France, UK, Germany, Switzerland, Poland, Hungary) and have proven their efficiency against almost all bacteria, yeasts, fungi, spores and virus especially towards the following: 



- H1N1 is a virus that was the most common cause of human influenza (flu) in 2009).

- Newcastle disease (H5N1 surrogate) is a virus subtype H5N1 which can cause illness in humans and many other animal species.A bird-adapted strain of H5N1, called HPAI A(H5N1) for highly pathogenic avian influenza virus of type A of subtype H5N1, is the highly pathogenic causative agent of  H5N1 flu, commonly known as avian influenza (“bird flu”).

- Legionella pneumophila is a thin, aerobic, pleomorphic, flagellated, non-spore forming, Gram-negative bacterium of the genus Legionella. L. pneumophila is the primary human pathogenic bacterium in this group and is the causative agent of legionellosis or Legionnaires’ disease.

- Mycobacterium terrae (tuberculosis surrogate) is a slow-growing species of Mycobacterium. It is an ungrouped member of the third Runyon (nonchromatogenic mycobacteria). It is known to cause serious skin infections, which are “relatively resistant to antibiotic therapy”.

- Staphilococcus aureus is a Gram-positive coccal bacterium that is a member of the Firmicutes , and is frequently found in the human respiratory tract and on the skin. It is positive for catalase and nitrate reduction.

- Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium responsible for several difficult-to-treat infections in humans.


Bio Technology


The build-up of friendly chemical environmental products

Our core values shape the culture and define the character of our company.

Tevan core values are to offer an efficient, reliable and innovative disinfection technology compared to the existing ones overly affected by long-term significant collateral effects.

Tevan takes an active part in the preservation of the natural basis of existence.

Accordingly, Tevan is developing environment-friendly non-toxic and non-polluting products within the current legislative and regulatory framework.

Tevan strictly follows appropriate protocol in order to accomplish its mandate within legal and ethical guidelines.




As part of the partnership undertaken with other companies, Tevan main commitment are the ones as following :

Tevan designs and develops chemical formulation & process through industrial and research partnership, as for example, universities and research centers.

Tevan organizes field-tests to validate new applications in the field of agriculture, fish farming (tomato cultivation, prawn), farming and wastewater treatments

Tevan develops new chemical recipes to respond to the ever increasingly polluting ingredients that make up the bulk of the today products.




The company is involved in the research, development, production and marketing of both preventive and curative cleaning & peroxide or peracetic disinfectants to fight pathogenic germs and organochemical constituents in waste.

Because pathogenic germs are capable of establishing their dominance; their presence indicates a disturbed or pathological state of the product (milk, cheese, etc) and organism (cow).

The recent development of new applications for peracetic acid – a disinfectant with little tendency to persist – and of biocidal applications are good illustrations to counter the threats posed by infections and increasing resistance to antibiotics.


As a matter of course, Tevan products are developed and manufactured consistent with the latest national and international regulations.

For all our products, refresher and updating courses are carried out and that include the changes in relevant national and international regulations concerning the safety and the protection of the environment and taking into account of any updating of the standard of the competency concerned.
