Hemp plastic industry pdf

They also have low saturated fats with rich sources of omega acids essential for good skin and hair and are used in several personal care products. The surging demand for hemp oil which helps in the prevention and alleviation of ailments is also predicted to drive the market. Rising health consciousness among the consumers along with the increasing trend of healthy food consumption, improving personal health is also likely to boost the market growth.

Hemp fibers being a renewable resource is been used in the production of daily use products such as paper, textiles, fuel, and bio-degradable plastics and the growing demand for eco-friendly products has significantly contributed to the growth of the market. However strict regulatory laws for the usage of industrial hemp in several countries prove to hinder the market growth.

Hemp is been legally banned in some countries and hence the manufacturers of industrial hemp find it very difficult in getting sanctions from the government and also find it difficult to price the products which would be affordable for maximum consumers owing to the limited market scope. At the same trend. Discussion Environmental and Economic Sustainability BEES [10], [13] The reviewed literatures suggest that hemp shiv have should be applied with projected information for hemp positive potential as eco-materials in the sense that they make production in Thailand.

However, for Thailand, However, for mass production more advanced technology sustainability criteria for promoting industrial hemp that should should be adopted and apply to ensure long term economic be considered should include land use change from food efficiency for the production process. Also, to ensure market production land to industrial hemp land as suggested by [], access of hemp construction products in Thailand, a survey [15], [22].

The 12 baseline sustainability indicators for assessing end-user requirements and acceptance level should sustainable construction materials suggested by [15] are be performed.

The mindset of the end-users in developing relevant but should also be customized for more details for countries like Thailand may not be willing to pay much more hemp.

Upcycling hemp shiv is an option to create green for eco-materials than what they are paying for conventional economy but the market demands and the economic viability materials even though they are aware of the climate change must be considered [5], [8], [19]. This is because hemp problem and environmental issues.

The survey may include production in Thailand is not industrialized and in order to questions that will help collect information which will be useful sustain the production of construction materials using hemp on for future design and development of construction products the industrial scale the environmental, economic and social from hemp.

It has the potential and International market such as Europe and North America where will contribute to lowering the carbon footprint of construction there are demands for hempcrete [17] may be an alternative material production and building at the end of use. The information waste material from the industry and support the circular can then be used to support decision making process in more economy and green economy concepts which are consistent to detail. Further studies will be The local details of each indicator should be further required to identify the appropriate mixture for construction identified and explore.

Using hemp shiv in its basic form may material using hemp and other agro-waste. However, some be a low technology production method but it offers physically materials such as rice husk or corn cob studied [4, 21] may not and mechanically usable lightweight eco-material product. More precise details on economic for reinforcement materials are also an option and further efficiency should be explored to verify the cost-effectiveness of studies are encouraged.

Non-cementitious based materials the investment. Further work From the above discussion and considerations, the Further work will include identifying sustainability indicators sustainability indicators for hemp shiv applications as eco- for industrial hemp production in Thailand based on the materials in construction based on suggested indicators by [15] sustainability indicators review using qualitative survey. This will that should be highlighted are suggested as follows. In parallel to that, the span of the material.

Conclusions The authors express sincere thanks to Thailand Research In conclusion, the reviewed literatures showed positive Fund for the Research Career Development RSA funding potential for using hemp shiv to produce eco-materials for support through the RSATheerawat Sinsiri project and construction in Thailand.

Main applications are concretes for manually compacted, casted walls, sprayed insulation coatings, external and internal plasters, premade blocks and panels for non load-bearing or load-bearing applications, floor slabs, slabs and roof insulation, including structural applications like vaults and cupolas. Whereas hemp consumption is unchanged, higher densities of kg kg are achieved, among other methods, with higher binder content [7] what increases the mechanical strength.

Those concretes and mortars are used in plasters, external renders and load-bearing applications. For environmental and economic reasons non calcined binders, e. It also contributes to temperature regulation by osmosis.

While aerial lime carbonates hardening progresses slowly and is very sensitive to climate conditions, hydraulic lime as well as mixes of aerial lime and puzzolanic aggregates are favorable options to accelerate the hardening process of a hemp concrete and allow setting with important coatings or wall thicknesses, without compromising the water vapor diffusion, compared to aerial lime binder.

While lime binder is even giving favorable results in humid climates, the uses of gypsum, un-stabilized clay and organic binders are limited or precise constructive measurements to protect them from water. Apart from greater setting problems than with lime or lime with small amount of hydraulic binder, Portland cement is not recommended as the only binder in a hemp concrete because of environmental aspects. Its energy demand during the fabrication process is higher than in hydraulic limes and only a very small amount of carbon dioxide, emitted in this process, is reabsorbed in its hydraulic hardening process.

On the other hand the addition of small amounts of natural cement to aerial lime can be useful during unfavorable drying conditions natural cement is a similar product to hydraulic lime but thanks to the composition of its raw material it hardens quick and develops important mechanical strength in a short period of time.

The innovative paper of hemp concrete as construction material is its function as a multi performance material, replacing entirely the mineral aggregates, used in conventional concretes [9], while in historic applications natural fibers where mainly added in meager amounts to concretes and mortars, e. While in the northern and central part of Europe formulations of this multi porous material are mainly designed to adapt to cold climate, thus are very light weight and depend from a wooden support structure, tendencies in the Mediterranean region focus on hemp concrete as a structural material with very dynamic thermal properties by adding a higher thermal inertia component.

This is to avoid very light and porous mixes with low or moderate thermal conductivities, ranging from 0. At the same time the need to import wood is drastically reduced, where this resource is limited.

The elimination of the structure is important in the total balance of the life cycle of a hemp lime concrete where the lime has the first and the wooden structure the second most important impact [11]. Final carbon footprint of a hemp concrete can be drastically reduced by replacing lime binders for clay binders, as the re-absorption of CO 2 of calcined binders is un-complete, also due to setting problems. In spite of a positive balance of all phases of their life cycle, a drawback in the use of plant based building materials like hemp concrete is still their higher purchase price, compared with conventional mainstream materials [12] and a general a lack of information and know how on this new technology.
