Editorial: Hawaii a good fit for hydrogen fuel

Hydrogen fuel is a clean-burning source of energy, and can be created from existing construction waste, agricultural byproducts and other organic materials. It can be used to power cars — and airplanes.



Future in fuel to take flight with the Aloha Carbon project

Simonpietri Enterprises’ Aloha Carbon project to create renewable jet fuel for the commercial aviation market is the first of its kind not only in Hawaii, but possibly in the world. READ MORE AT PACIFIC BUSINESS NEWS.


Hawaiʻi renewable fuel firm receives $1.6M from US Department of Energy

Simonpietri Enterprises has received $1.6 million dollars to generate clean hydrogen fuel out of construction and demolition waste.

Learn how Aloha Carbon is planning to reduce Hawaii’s landfilled waste while helping to pave the way for a more sustainable tourism industry in Hawaii. WATCH HERE or click on the video.

focused on local sustainability

Our mission is to do something better with waste than to dispose of it in landfills.  The Aloha Carbon project was created to help Hawaii’s energy transition to climate-friendlier bioenergy options, by delivering waste management solutions that reduce dependency on fossil fuels.  We are the recyclers of what cannot be recycled!

We focus on our biggest local needs, which have the least amounts of solutions: finding alternate uses for construction and demolition debris(C&D) and organic urban wastes, and converting them into green hydrogen and sustainable aviation fuel.

What we do:

Waste Diversion

Similar to recycling, where materials are used in a new way, waste diversion makes use of materials away from landfills.



Gasification can also be used to process waste, but it is a chemical process instead of a combustion process. This difference allows for higher emission controls. Unlike incineration, there is potential for gasification to deliver negative Green house gas (GHG) emissions.

Carbon-Neutral Growth

Aloha Carbon is aiming to help airlines serving Hawaii meet their goals of  carbon-neutral growth. This includes producing renewable fuel and carbon credits that meet the United Nations’ International Civil Aviation Organization Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) requirements to hold lifecyle greenhouse gas emissions at 2020 levels – including flights to and from Hawai`i.

What we do not do:

Throw away waste

A landfill should be the final stop for waste after all recycling options have been exhausted. When landfills are full, new sites need to be created, which can affect local communities.



Incineration is to burn something completely and reduce it to ashes. An incinerator is a device that directly “burns” feedstock, and is a form of processing waste. There are over 50 incinerators in the US.

carbon-Intensive growth

We aim to reduce carbon-intensive economic development by displacing fossil fuel,  raw material imports,  and greenhouse-gas intensive cement and building materials,  with careful sorting and recycling of waste into locally sourced building materials and energy products.
