Transcript:
Audio from news clips about hemp.
Alie Kilts: America has become hemp obsessed.
Ava Robinson: But we’re here to get hemp critical. I’m Ava.
Alie: And I’m Alie. This is Trace Material a new podcast from Parsons Healthy Materials Lab at the New School.
Ava: The stuff in our walls, furniture, and clothes have a big effect on our bodies and our environment… they also have stories to tell.
Alie: We’re going to trace the history of the materials we surround ourselves with, and see what they reveal about the way we live our lives.
Ava: This season we’re digging into all things hemp. For as long as this country has existed, hemp has been deeply ingrained in its culture.
Kathy Nichols: And hemp, by the way, is the reason slavery is entrenched in Kentucky.
Cassandra Sea: Yeah, the very same thing that brought prosperity to the family that raised hemp was the same thing that whip the slaves that broke the hemp and that was just the, it was just crazy, the cycle.
Alie: Hemp’s gotten caught in the crossfire of some of America’s most infamous crusades.
“(gong sound) Marijuana! The burning weed with its roots in hell! … - Reefer Madness
Alie: We’re going to untangle the web of cannabis and dig into the details.
Ava: And after all that, we’ll see what the future holds.
Winona LaDuke: And so what I want to do is to talk about how we are going to build a post petroleum economy. And that has to be built with something like hemp.
Alie: Trace Material launches on April 8th. Don’t forget to subscribe!

About Our Collections
The goal of our collections is to help promote transparency in the material ingredients of building products by fostering knowledge and awareness of products and materials for which life-cycle information is available, and that have environmentally, economically, and socially preferable life-cycle impacts.
Keep an eye out for the following symbols:
A Healthier Affordable Building Product
Products with the designation of "Healthier & Affordable" were specified and installed in at least one of our Case Studies of healthier affordable housing.
Available at the Donghia healthier Materials Library
The Donghia healthier Materials Library library is open to Parsons student and faculty. Learn more about access and opening hours here.
Low Embodied Carbon
“Embodied Carbon” is the total amount of carbon emitted during the process of making a material. *HML refers to a manufacturer's EPD to determine whether a product's A1-A3 carbon emissions falls within HML's threshold for Low Embodied Carbon.
New Product
This product has been added to the collection within the past six months.
Product in Development
Products with this designation identify they are currently scaling or only available in markets outside of the building industry. they could be experimental or in use in capsule collections.
Available in the EU
Products with this designation are currently available only in the European Union and identified as being an exemplary healthy option in the respective product group.
Ingredient Disclosures
There are several ways of evaluating a material’s health that we include with product information. Disclosures are reports by manufacturers about product ingredients, impacts, or other attributes.
Key Disclosures include:
Health Product Declaration (HPD)
A voluntary technical specification for reporting information on product contents and associated health information, intended to be the health-analogue to Environmental Product Declarations (EPDs).
Declare Label
Declare is a transparency platform and product database that answers three questions:
1. Where does a product come from?
2. What is it made of?
3. Where does it go at the end of its life?
Environmental Product Declaration (EPD)
A standardized format for communicating the environmental effects associated with a product’s raw materials extraction, energy use, chemical makeup, waste generation, and emissions to air, soil, and water.
Safety Data Sheet (SDS)
A reporting format that provides basic information about a material’s chemical ingredients, the potential safety hazards to installers, and recommended practices for installation.
USDA Certified Biobased Product Label
Managed by the U.S. Department of Agriculture (USDA), the goal of the BioPreferred Program is to increase the purchase and use of biobased products.

| The Real Milk Paint | Hemp Oil |
Hemp OilAvailable At the Donghia Materials LibraryHemp oil is a healthier finish and works particularly well on wood. The Real Milk Paint’s Hemp Oil is free of additives, preservatives, solvents, and VOCs. It is thinner than tung oil, making it easier to apply without the addition of a solvent. However, hemp oil is less durable and waterproof than tung oil. Hemp oil is food safe and works especially well on lightly used items.

| IsoHemp | Hempcrete Block |
Hempcrete BlockAvailable At the Donghia Materials LibraryIsoHemp’s hempcrete blocks are a non-load-bearing masonry product. These natural, healthy blocks are designed to be used for insulating envelopes, partition walls, and counter-partitions. Made only from hemp and lime, hempcrete’s ability to diffuse accumulated heat makes it a fantastic thermal regulator. This product also regulates humidity due to its permeability and is naturally very fire-resistant, making toxic flame retardants obsolete. Not only are IsoHemp hempcrete blocks good for human health, they also have a positive environmental impact. Their manufacture requires very little energy, and they act as a carbon sink, actively absorbing CO2 from the air. CategoryMasonry, HempcreteManufacturerIsoHemp
