Basics

New MeWa technology processes a new product out of used tyres

Unbeatable advantage compared to ambientor cryogen processes

ActiMeWa creates an independent bond without additives

Rubber products can be produced only bytemperature and pressure

Can replace rubber by 20 to 60%Can replace rubber by 20 to 60%

Market prices significantly higher than granulate prices

Absolutely free of textile fluff and steel: Looks no different to original rubber

Brand ActiMeWa

Wh t k b d t ?What makes a brand strong?

Product name becomes generic name:The product brand takes root in customers head and becomes general linguistic usage.

Examples:

Tissues = High pressure cleaner =

Vacuum cleaner = Searching on the internet =

Kärcher

Verb „to google“Hoover



Brand ActiMeWa

Active rubber crumb = ActiMeWa

ActiMeWa stands for:

High market pricesThe pre purchase risk to buy investment goods is reduced through a strong product!

Quality

reduced through a strong product!

The unique selling proposition (USP) for a tyre recycling plant:

ActiMeWa

Characteristics

Active rubber crumb:small with a rough surface

Granulate:smooth surface, sharp edges



Differences between cryogenic and ambient fine grinding

Cryogenic process:

Granules are cooled with liquid

nitrogen making them very brittle

Conventional ambient process:

Rubber ground at ambient temperature

Works like the cryogenic process onlynitrogen, making them very brittle

Very small grain sizes achievable

Due to smooth surface it cannot

Works like the cryogenic process, only

without the addition of nitrogen

Grain size bigger than the achieved

be used as natural rubber substitute

Application areas include additives

gg

with cold grinding

Process is cheaper than cryogenic

for paints

High prices for liquid nitrogen makes

it difficult to operate such plants

Applications are very similar to granules

Better looking than coarse granules

it difficult to operate such plants

profitably



Application in road construction

Due to its resiliency ActiMeWa can be used as a real additive for the asphalt covering in road construction

ActiMeWa replaces expensive Polymer-additives

Further advantages in road construction:

low-noise level

Best drying after rain and snow

High resilience and longer life timeHigh resilience and longer life time, therefore low costs of maintenance



Application in road construction

The advantage of rubber crumb in road construction:

• Road with conventional asphalt • Road with rubber asphalt

• 8 year old asphalt covering

• cracks (repaired) in evidence

• 8 years old, too

• Obviously better road conditions



Application as rubber moulded products

Industrial applications
