Our boards and planks are the perfect wood substitute building material that do not involve destruction of forests or contain any toxic chemicals, resins or glues.
Tackling the Problem at Source
The ‘green’ aspects of the SHERA Fibre Cement building materials begin long before the manufacturing process even starts. SHERA in fact design their own production machinery with the ‘green policy’ first and foremost in their in minds. Machines at manufacturing plants are designed to reduce noise pollution, recycle water and waste sediment, reduce air contamination by dust and noxious fumes and also reuse cast off materials generated through the production life cycle.
Using Local and Recycled Raw Materials
SHERA environmentally friendly building materials are produced using a process which utilizes local raw and waste materials to protect the environment, enhance the properties of the product and reduce production costs.
The fibre cement manufacturing process requires two essential elements at various stages in the life cycle: cellulose pulp and heat.
Farmed trees: The production process used for SHERA fibre cement products uses pulp from farmed trees only. Under no circumstances are any natural forests decimated as a result of using these raw materials.
Recycled paper: In addition to this, a high percentage of the pulp used comes directly from waste paper supplied from various paper based industries around Thailand.
Eco friendly fuel: In order to generate the heat required during the manufacturing process the SHERA technologists came up with the ingenious idea of using rice husks, a common waste material from the numerous rice mills in the region.
This generates valuable income for the local rice farming businesses and uses their waste product to generate the heat required instead of using methods which are more damaging/polluting to the environment.
Environmentally Friendly Building Materials
SHERA have operated under a strict “Green Policy” for many years and operate under the concept of manufacturing an ‘environmentally friendly’ building material using eco friendly manufacturing processes.
The SHERA fibre cement manufacturing process creates very little industrial ‘mess’ – dust, oil, dirt ,ie normal, unfortunate byproducts of industrial scale manufacturing.
This is due to a number of innovative technological solutions implemented by SHERA over the last several years. Some examples are:
Course sand needs to be ground, which normally causes a lot of pollution. At SHERA we utilise a special ‘wet process’ for sand grinding which results in zero dust pollution and in addition the water and sediment are collected and reused.
Steam produced as a result of the manufacturing process is passed through specialised filters to extract noxious smells and reduce hazardous conditions in the workplace.
Noise levels in the plant are also unusually low. This is a direct result of innovative designs in fibre cement manufacturing machinery, which helps to create a less hazardous workplace for staff as well as reduce noise pollution levels for inhabitants in the surrounding areas.
Recycling Waste Materials
There are several areas in the fibre cement production process where the SHERA production machines / production process make use of unavoidable wastage. Steam produced in heating process is re-used in the product curing process.
Waste material from burning rice husks is recycled into the product.
Water is recycled into vast ‘ponds’ and reused in the product manufacturing process.
Dust and sediment which accumulates during the manufacturing process is mixed with the pulp and returned to the product.
Wastage such as trimmings caused by the cutting process are ground and returned to the product.
