Frequently Asked Questions

Q. How big is the PVT facility?

A.  The entire facility encompasses about 135 acres. Only a small portion of that is engaged in landfill operations at any given time. The landfill face is located in the interior of the facility, about a half-mile from the neighboring residential community.

Q. What kind of debris does the PVT facility accept?

A.  We accept non-hazardous materials from construction or demolition sites, which includes but is not limited to wood, metal, plastic, concrete, asphalt, glass, masonry, roofing, rock, dirt, boulders, and siding.

Q. Does PVT accept tires, appliances, or car parts?

A.  No. Nor do we accept pesticides, medical waste and many household items that are classified as hazardous waste. For a complete list of prohibited materials, click here.

Q. Does PVT accept asbestos?

A.  We do not accept asbestos. However, we do accept asbestos containing materials (ACM) provided they meet strict conditions for disposal. Each asbestos load accepted for dumping is escorted and directed where to dump. Only ACM that has been double-wrapped in 6mm plastic is allowed in the asbestos pit. Fortunately, asbestos is no longer used in construction and is typically found only in older buildings, which are becoming fewer.

Q. How much debris does PVT recycle?

A.  At full capacity, the PVT recycling system is capable of processing 1,775 tons of debris for recycling every day. That total includes 42 tons of metal, 900 tons of feedstock for energy production, and 840 tons of rock, concrete, and dirt. The remaining 200 tons cannot be recycled and would be put in the landfill.

Q. What is feedstock?

A.  Feedstock is wood, plastic, paper, cloth and other materials that are suitable for bioconversion in a gasification process. These materials are separated, crushed and shredded into pieces about four inches or smaller in size. They can then be shipped to a gasification facility where they can be burned in a process that manufactures synthetic gas.

Q. Who is using the feedstock?

A.  Right now, the feedstock is being stockpiled for eventual use in a gasification process. A gasification facility is now in the planning and permitting stages. PVT has an agreement to supply feedstock to the facility, which in turn has a power purchase agreement with HECO to purchase gas when the facility begins operation.  In the meantime, we will continue to process feedstock in preparation for its use.

Q. How much feedstock can PVT produce?

A.  The PVT recycling system can process up to 900 tons of feedstock per day. That’s enough to produce three times the amount of synthetic gas needed in Honolulu every day.

Q. I’ve heard that PVT plans to reclaim debris that’s buried in the landfill. What’s that all about?

A.  It is estimated that there are about four million cubic yards of C&D debris in the landfill. Now that we’re running a high-capacity recycling system, we can reclaim, process and reuse or recycle much of what went into the landfill years ago. Much of what is reclaimed will be processed for use as feedstock.

Q. Do taxpayers have to pay for operations at the PVT facility?

A.  No. Unlike the Waimanalo Gulch municipal landfill, the PVT facility is privately owned and operated and requires no taxpayer funding.
