5 Reasons India is Not Ready for Hempcrete... Yet!

Hempcrete has been one of the most researched building materials in the recent times. The staggering amount of research literature being published almost every month hold a light to that fact. As a matter of fact, our Indian shores weren't immune to it either. Several entrepreneurs have been taken hostage by the mania and have forayed into the world of hemp. And one of the most talked about hemp products is hempcrete. But is India really ready for it?

We have an entirely different construction methodology.

Modern hempcrete was conceived to function as a thermal insulation material for the temperate climes where sub-zero temperatures are a fact of the day. With huge per capita carbon emissions of countries belonging to these climatic zones, it was important to develop a natural insulation material that is moderately strong and energy efficient. Another requirement was that it was needed to be compatible with their timber frame structures. Thence, in most European applications of hempcrete you will find that it is placed as an in-fill in timber-stud walls. The Indian applications are decidedly different. Our conditions are harsher and our locally available materials are different. The stresses our building materials are subjected to are several degrees higher.

We do not yet have a hemp industry.

Manufacturing and marketing of hempcrete is predicated on India having a hemp industry. While the Indian State of Uttarakhand has legalised the cultivation of hemp for industrial purposes, we do not yet have those cultivars of hemp that have a THC content of between 0.3% and 1.5% to satisfy the conditions of the state hemp policy. Importing seeds from abroad is obviously expensive and is not a sustainable business model. This affects the production of the hemp shivs which are used to make hempcrete. A 1000 sq. ft. hempcrete house needs produce from about 1 hectare of hemp cultivation.

Its properties are not validated in India.

As mentioned earlier, there aren't any constructions in India that are validated by scientific investigations to prove its suitability for adoption by the Indian consumers. Even the most basic material characteristics of hempcrete when manufactured in India are not determined. We do not yet know how it shall behave when it is produced with locally available materials. Needless to say, the manufacturing processes aren't standardised either, resulting in inconsistent material behaviour.

Hempcrete is not recognised by Indian Authorities.

Hempcrete is a variety of vegetal concretes, an emerging class of building materials being actively developed and used in countries like England, France and Belgium. Their authorities have formulated certification and authorisation procedures for the manufacture and use of materials like hempcrete. In India, such materials are not in great use and public organisations haven't taken it upon themselves to promote or recognise them. Public organisations such as BMTPC are responsible for the promotion and adoption of innovative building materials and technologies.

Building with hempcrete requires a different skill-set.

The consistency and characteristics of hempcrete are different from other building materials such as AAC blocks or fly ash bricks. Production of hempcrete involves raw materials such as lime and plant particles, which local engineers, masons and construction workers are unfamiliar with. For example, traditional building materials involve water curing, whereas lime products require air curing. The revival of traditional knowledge is the biggest challenge when building with hempcrete. Hempcrete houses also require unconventional finishings which may require greater skills.

As you might have already realised, the "impediments" to the adoption of hempcrete in India are not really impediments. With enough time and focused efforts, we can easily start building with it. GreenJams Infrastructures LLP is at the helm of these efforts leading the path to setting up hempcrete for faster adoption by Indian consumers. Please feel free to get in touch with us to learn how you could have your very own hempcrete home.

India’s Need for Hemp: Carbon Emissions Context

The latest World Bank records show that India’s per capita CO2 emissions in the year 2014 were 1.73 tonnes of CO2 per person. A 2017 report by the PBL Netherlands Environmental Assessment Agency had shown that it was 1.80 tonnes of CO2 per person in 2014 and it grew to 1.91 tonnes of CO2 per person in 2016.

Interestingly, while the representatives of the 196 parties to the UN, in a rare consensus have agreed to cap the increase in global temperature to less than 1.5OC at the Accord de Paris, there is an interestingly rarer consensus amongst the scientific community that geoengineering is the way to go.

5 Reasons Enterprising Builders Should Consider Hempcrete

It is a bygone conclusion that hempcrete is amazing. In fact, when you consider it, there arguably isn’t any other building material that has enjoyed as much approval in recent times. But if you’re a builder why should you care for this?

How Hemp can Help India Achieve its Sustainable Development Goals

It is a racing certainty that businesses have an important role to play in preventing climate change. But businesses are predicated on profits, and not long ago, entrepreneurs considering businesses that incorporate climate solutions were thought to be “hare-brained”. However, things have been changing gradually. Ever since the recent re-emergence of the trillion-dollar crop – hemp, dispositions are starting to look good for both climate and entrepreneurs.

WINNERS! Clean Energy Challenge: What Design Can Do

It was just 2 days until deadline when we discovered the Clean Energy Challenge through some friends of ours. A little reading about the challenge, the organisers and supporters got us supremely excited. Not everyday do you get an opportunity to be a part of something that gets supported by the IKEA Foundation and endorsed by the UNFCCC. Not just that, the challenge brief fit our solution so well, there wasn't an option other than applying for it.
