Do I need a clearance form to drop off material?

Yes! We are happy to report the fastest turnaround time in providing clearance forms on Maui. You can download the form here. Please make sure you save and open it to complete the required fields.  After completion you can email it back to us at

Do you take green waste?

No,  Hawaii Materials Recycling does not take green waste. On Maui, you are allowed to take green waste to the landfill.


How are you different from the landfill?

The local Maui landfill accepts trash, green waste and other materials considered suitable for dump.  We only accept certain materials like rock and dirt left over from projects like a house build or landscaping. We also accept asphalt and concrete from road construction and demolition.  We follow protocols and screening to ensure the materials we accept are not contaminated and meet our standards. We also require forms to be completed on where the material originated from. In addition, there are recycling centers on the island that accept cardboard and metal.

Do I have to work in a commercial setting to use


No! We welcome big and small projects alike.  Whether you have a residential landscaping project and need some dirt, or a new home construction and want material cleared, reach out and we can assist you.


What if my rock and dirt have grass or rubbish mixed in with it. Is that OK?

Screening will be conducted to ensure there is no rubbish or green waste co-mingled. A $75 re-loading fee will be assessed for any unacceptable material. 

What form of payment do you accept?

Visa, Master Card, Amex and cash

Can I pick up a bucket of top soil or fill for myself or do I need to hire a hauling company?

We welcome everyone to Hawaii Materials Recycling. If you don’t need a large load and you would like to fill up a few buckets or the back of your truck, we can help you with that. If you decide you would like much more material or it’s just too much weight for your personal vehicle, we can assist with hauling as well. We do however, prefer that you come at the end of the day when there are fewer trucks. To help us plan ahead please call to let us know you are coming. Call our office for details at 808-856-6231.

Do you offer delivery and pick up?

Yes! We can assist with hauling. We do not have our own trucks however we work with several reputable companies. Call our office for details at 808-856-6231.

Are you open on weekend and holidays?

We are not open on weekends or most holidays, however, when possible, we can open on special request. Call our office for details at 808-856-6231.

Are you a quarry?

No! We are not a quarry and we do not blast or shoot the earth to create aggregate. All of our aggregate materials sold are made from inert waste brought to us in the form of concrete, asphalt, sand, rock and dirt. We go through an extensive process to recycle it and then make it available to you.  By offering clean recycled material we are not taking anything from the land, only repurposing materials already used. 


What is inert materials recycling?

It is a process of reusing materials that do not decompose under normal environmental conditions. Examples include concrete, bricks, asphalt, dirt and sand. By recycling these materials, we can reduce waste and conserve natural resources.  Rather than sending these materials to the islandʻs limited landfills where they take up valuable space and contribute to environmental pollution, they are repurposed for other applications like road construction. This is also important when it comes to cost and eliminating high overhead of brand new materials.

What is waste reduction?

Waste reduction is crucial to our ecosystem.  By using recycled material and keeping it out of landfills, we can help to reduce greenhouse gas emissions by avoiding the energy-intensive process of extracting raw materials out of quarries. Overall, recycling these materials can be an important part of sustainable waste management systems. Hawaii Materials Recycling aims to reduce waste, conserve natural resources and minimize environmental impacts to the island.

If your construction, demolition, and land clearing materials are currently being sent to a landfill, your disposal costs may be unnecessarily high. The tipping fees at HMR are considerably less than those of the county landfills. Transport costs are also another concern among contractors; often trucking costs are cut in half by coming to our site in Central Kihei.

Waste Reduction

For a successful C&D waste reduction program, we need to educate the public, businesses, developers, contractors, and architects to use less and still achieve success. When designers and builders understand the negative impact that waste has on the environment, and the positive impact they can make in their efforts to reduce waste, they can be more proactive. Architects must think ecologically about their projects and should design to use less. There are a number of questions architects may consider when specifying a product in the design of a project:

  • Does the design or construction process reduce waste?

  • Do the products specified include recycled content?

  • Does the project use locally available and often overlooked resources?

  • Are the products or materials specified easily recyclable?

  •  Can the products or materials specified be easily reused or salvaged?

Waste Recycling

How about recycling? Take scrap lumber that cannot be reused due to its size or condition, then cut, press and glue it together into press board—you are recycling it. The wood fiber has gone through a re-manufacturing process. Recycling requires energy and may have environmental implications when materials go through re-manufacture. Therefore, reuse is generally preferred over recycling. But recycling can provide significant benefits over making the product from virgin material. Today's waste entrepreneurs use heavy-duty, industrial materials. Current efforts in C&D waste reuse and recycling by Hawaii businesses include:

  • Excavated Dirt: used for fill or topsoil.

  • Excavated Rock: used for decorative walls or road base material.

  • Non-Lead Based Painted Concrete: crushed and used for road base, backfill or sub-base for building construction.

  • Asphalt concrete: crushed for use as aggregate, road base or new asphalt concrete.

  • Untreated Wood Waste: reused as pallets, or ground into mulch or biofuel.

  • Green Waste: ground for use as mulch for compost.

  • Steel: processed for shipment to steel mills out of state.

  • Cardboard: baled for shipment to paper mills out of state.

Managing C&D Waste: A Checklist

CONDUCT AN INFORMAL WASTE AUDIT Determine the amounts, types, and time-frame for construction and demolition materials generated by your projects. Calculate any possible cost savings from reducing a portion of this waste, in terms of hauling and disposal cost avoidance.

REDUCE- Look at strategies to reduce construction and demolition waste volumes. Proper materials management practices may result in cost savings. Assure that precise estimates are made prior to purchase of materials, and that accurate measurements are made prior to cutting materials so that excess scrap and end cuts can be avoided. Consider having materials pre-cut at lumber yards, using engineered wood products, steel framing, or other pre-manufactured components. Work with suppliers and subcontractors to minimize excess packaging and other non-essential material from being brought on site.

REUSE-  Consider the potential for others to use the materials you normally discard. Consider planning ahead and calling Aloha Shares Network, Habitat for Humanity or other non-profit organizations.

Beginning a Construction and Demolition Recycling Program

The first step is to find out the quantities and the composition of your waste; the time frame in which waste materials will be generated; and the amount of space available for separation of materials at the site. Then with this information, you can begin to determine what wastes will be generated and if quantities will be materials and/or arrange donations. This can provide your company with significant enough additional tax deductions. Conduct site pre-assessments for demolition projects to evaluate what materials can be salvaged for reuse, such as cabinets, architectural woodwork, light fixtures and appliances.

RECYCLE- Investigate the companies listed in this guide that can recycle some of your construction and demolition waste from either source-separated or mixed loads. Compare the costs of recycling with the costs of disposal. Contact haulers. They may help you set up an effective separation program. Work with your subcontractors to keep recyclable scrap from being mixed with trash during clean-up.

EDUCATE EMPLOYEES, CONTRACTORS, AND SUBCONTRACTORS-  Whatever waste reduction strategies you choose, it is crucial to educate and motivate employees and subcontractors for maximum participation. Emphasize that source reduction, reuse and recycling is everybody's business.
