DISSERTATION 2020 SPA DELHI
In the above framework, all 17 Sustainable Development Goals try to figure out their contribution types, names and they are contributing to SDGs. Bamboo can help in achieving Goal no 3 by enhancing the medical infrastructure. By reducing carbon footprint, they can help in achieving Goals like 7, 11 and 13. By creating partnerships they can achieve Goal 17, by reducing the consumption and production they can achieve goal no 12 and they can also help in achieving Goal no 8 by creating Jobs.

Hempcrete is a lime-based binder consisting of hemp shives. Hemp is generally named as plants that are widely used for industrial purposes like textile, food, plastic paper etc. Hemp is referred to as carbon negative for its agricultural roots and use of lime as well as other industrial waste as mineral binders. A study finds that hemp, which fulfils the role of preventing insect activity, was present in the lime and plaster of Ellora caves, over 1500 years old Hemp has some extraordinary qualities and researchers discovered that the mixtures contained at least 10% hemp

fibres, which made it bind better, make it insect resistant and also helped to regulate the humidity inside the cave (SINGH et al, 2017). 3.3.1 Properties of Hempcrete
The hemp is majorly divided into two parts.
● Bast
Bast fibres are normally extracted from the hemp straw's retting process and woven into textiles, belts, ropes, etc.
● Hurd
And so far, the Hurd plant has been used as insulation and bedding for animals etc. While, it is also referred to as shivs that are used for purposes of cellulose. Hemp is among the most commonly known and utilized researched material particles in building construction production and hemp is one of the most thoroughly investigated bio-based concrete.
3.3.2 Carbon Footprint and thermal performance
The structures are much more concrete, metal and some other materials in modern days, which they've been produced or cultivated for decades. Concrete output produces CO2, which is the material commonly used in construction. A potential alternative replacement.
Normally, hemp sequesters carbon both within the plant themselves and through sequestering carbon throughout the ground. The quantity of sequestered carbon depends on the characteristics of hemp, when and how it has been produced, and how it has been extracted. It is considered as hemp preserves an approximate 325kilograms of carbon per metric ton of composite hemp.
The hempcrete's thermal conductivity indicate that the scale of a heating plant can also be decreased, reducing the resulting energy consumption and carbon emissions, which may be between 50% and 80% lower than in buildings of traditional concrete blocks structure heated to

the very same U-value as the hempcrete structure. Standard 12-inch-thick walls just provide necessary R-value (~2.5/in.).
3.3.3 Hemp Contribution towards Sustainable Development Goals (SDGs)
Hemp is considered to be a sustainable, non-toxic, green yet low-energy material that during development requires no chemicals and much less irrigation and fertilizers and pesticides than cotton. If, building Industry built their structures with hemp material, definitely hemp will become one of the most eligible sustainable materials for the environment. However, these Goals can be directly and indirectly achieved by the using of hemp as a building material.

In the above framework, almost each and every goal is contributing directly or indirectly to SDGs. Hempcrete can help in achieving Goal no 3 and 4 by enhancing the medical, school infrastructure. By reducing carbon footprint, they can help in achieving Goals like 7, 11 and 13. By creating partnerships they can achieve Goal 17, by reducing the consumption and production they can achieve goal no 12 and they can also help in achieving Goal no 8 by creating Jobs.
