An example of the ridiculous clap-trap perpetrated by the climate change crowd. There isn’t enough pine resin to make even a small dent in the world’s use of energy; it would likely take more energy to gather up the pine gum than you could get out of it; and how would you replace the rosin used for adhesives, inks, coatings etc? With petroleum hydrocarbon resins?
[PDF]Modification of cleaning product formulations could improve indoor air quality
N Carslaw, D Shaw - Indoor Air, 2022
Cleaning products contain numerous individual chemicals, which can be liberated
on use. These species can react in air to form new chemical species, some of which
are harmful to health. This paper uses a detailed chemical model for indoor air …
Interesting article to us in PCA because pine oil contains very little alpha-pinene or limonene. However, the other terpenes may react in the same way.

Compositions for controlled release of active ingredients and methods of making same
United States Patent 11278023 B2 · Filed: 09/20/2019 · Published: 03/22/2022
Assignee:
Hazel Technologies, Inc. (Chicago, IL, US)
Inventors:
Preslar, Adam Truett (London, GB)
Mouat, Aidan R. (Chicago, IL, US)
FIELD OF THE INVENTION
Compositions for controlled release of active ingredients and methods of making same are generally provided.
BACKGROUND
Produce waste throughout the supply chain decreases agricultural productivity and reduces the availability of nutritious food sources. Produce ages and eventually spoils due to, for example, one or more of the plant hormone ethylene, bacteria, microbes, fungus, and other pathogens. Volatile or gaseous active ingredients including, but not limited to cyclopropenes, essential oils, terpenes, and terpenoids can be used to control produce spoilage, but their inherent volatility in the gas and vapor phase limit their usefulness. Accordingly, improved composition and methods are needed.
SUMMARY OF THE INVENTION
Compositions for controlled release of active ingredients and methods of making same are generally provided.
In some embodiments, a composition is provided comprising a delivery material selected from among the group consisting of carbon materials and silicate materials; and a volatile or gaseous active ingredient useful for applications in at least one of agriculture, pest control, odor control, and food preservation present in the composition in at least about 0.01 wt % versus the total weight of the composition, wherein the composition is configured to control release the volatile or gaseous active ingredient.
In some embodiments, a composition is provided comprising a silicate material comprising a surface area greater than about 1 m2/g; and at least one active ingredient selected from the group consisting of essential oils, terpenes, terpenoids, carvone, thymol, hexanal, carvacrol, oregano oil, and thyme oil, and combinations thereof. This appears to be the new development.
