Wood chips covers

A secure covering with Toptex protection fabric for wood chips enhanved the storing of wood chips at a dry and cost effective level. An optimum energy yield is achieved when safely improving the storing of the wood chips before taking advantage of their energy characteristics. In order to actually gain the optimum energy yielf from wood chips as an energy resource, ist moisture content must be limited to a minimum. In the absence of effective covering, like Toptex protection fabrics, this would alternatively have to be done by constructing a cost expensive roof structure.

With a safe protection like Toptex, water shedding and respiration of the wood chips are no longer unreachable. Toptex drains off water along ist surface, while the wood chips remain perfectly dry*  (*only extreme and unusal precipitation can temporarily result in partial moistening of the wood chips). Since Toptex is resirating, the wood chips just easily dry off and moist air that could be cummulated by the warming up of the wood chips themselves can easily penetrate through the fabric resulting in solid temperature below the pile.

Main Benefits

Toptex facilitates the cost efficient outdoors storage of wood chips, thereby the construction of expensive halls or roofs is no longer necessary and saves up the otherwise occuring costs thereof. Additionally, in case of windy weather, Toptex also protects neighbouring properties-the development of dust particles created from the wood chips is significantly reduced.

Furthermore, Toptex can easily be cut into the required sizes. It is made of continuous polypropylene filaments that are not chemically harmful to the environment and tested. The fabric is consequently decay resistant and due to its enhanced UV stabilization of the polymer, thus resulting in a life expectancy of up to 5 years.

It is therefore the combination of the following characteristics that make Toptex the perfect solution to cover wood chips:  

• Toptex allows respiration of the pile  
• Toptex effectively sheds rain water 
• Toptex is proven to be wind resistant 
• Toptex is visually attractive due to its green colour that blends in with the surrounding environment  
• Toptex has a longevity of 5 years  
• Toptex is the most economic while improving the product quality.   

The positive effect of an effective covering of a wood chips pile with Toptex was also proven by a test carried out by the Bavarian Forestry Institute in Germany.   

In short: Toptex is the economic solution for the outdoor storage of wood chips! 

The Toptex protection fabric for wood chips cover protection is made from green, continuous polypropylene filament in 200g/ m² and available in the following sizes:
4 x 50 m
5 x 50 m 
6 x 50 m

Composting covers

The controlled composting of organic waste with the Toptex protection fabric leaves odour emissions at bay and increases the quality output significantly. Composting is the conversion of organic wastes into high quality humus. Through systematic controls these materials can be returned to the earth, completing the cycles of nature and improving the soil to which it is applied.  

To achieve this goal, strict guidelines and controls must be followed. This includes the proper selection of the feedstocks, regular turning of the piles for aeration and proper guidance of the decomposition process.  Therefore, several parameters such as temperature, oxygen levels, CO2 levels, pH value, sulfide, nitrite, nitrate and ammonium must be continuously monitored, and if necessary, adjusted.  Due to its physical characteristics, the Toptex compost protection cover is an important tool in this optimal composting process.

Toptex possesses over a decade of experience in agriculture related applications world-wide. Toptex compost protection covers have proven themselves in composting sites around the world, and belong to today’s state of the art regarding modern composting technology. Many windrow turners are now serially equipped with specific fleece rolling devices to meet their clients demand for a perfect integration of the Toptex fabric into the composting process. 

Experienced users even started to implement the Toptex protection fabric to cover their most valuable product: the mature compost. This is not only an economic solution, but also very easy to handle. The cover fabric allows the exchange of gases, protects against moisture,keeps the compost dry and in a crumble structure, just as it is supposed to be. It furthermore efficiently protects the mature compost against the growth of all kinds of weeds that might otherwise start to seed into the compost. 

But Toptex can not only be used to cover mature compost, but also for raw manure. Scientific studies show that nutrient losses can be reduced significantly with Toptex protection fabric at hand. Several Government guidelines and best management practices recommend the covering of stacked outdoors manure with Toptex composting fabric.

Main benefits

Since Toptex is a gas-permeable fleece fabric composted of continuous polypropylene filaments, it is environmentally compatible (certified). The fabric can be recycled and is chemically stable against acid and alkali (pH 2-13). Toptex is furthermore biologically stable against microbial decan and leachate, while also being freeze and thaw tolerate. Toptex composting fabric is also UV resitant due to its special stabilization and will normally have a lifespan of 3-5 years under European climate conditions, however, if it is protected from UV raditiation when not in use, the life span can be extended. 

The main benefits of Toptex fabric can be therefore characterized as maintaining optimal moisture conditions, since Toptex diverts rainfalls away from the composting and safely protects the resources from drying by sun or wind. 

Toptex furthermore ensures a proper aerobic decomposition. As the Toptex protection fabric allows the necessary gas exchange and thereby ensures an even more optimal temperature throughout the outher layers of the composting piles. Toptex also minimizes leachate and nutrient losses as it diverts the rainfalls simply away from the windrows and therefore decreases the potential of leachate. 

Another important aspect for implementing Toptex into the composting process is the reduction of odour emissions. As Toptex supports an optimum an-aerobe decomposition process, it thereby also reduces the odour emissions to a minimum. 

The Toptex protection fabric for composting cover protection is made from green, continuous polypropylene filament in 200g/ m² and available in the following sizes:
