Customers seeking waste management outcomes will assess PacPyro in conjunction with other advanced waste management technologies including tunnel composters and bio-digesters.
Organisations and local governments are being driven towards more stringent environmental standards and are seeking alternatives to landfill, landfill bioreactors and incineration. Incentives are also in place through national carbon reduction schemes to redirect these waste flows in an effort to avoid the production of methane, a potent greenhouse gas. PacPyro’s technology provides significant resource recovery benefits with many feedstocks, in addition to the potential emissions credit from landfill avoidance. The technology can also achieve significant volume reduction of problem waste materials (70-90% reduction in material based on wet tonne weight).
Composting has become central to techniques adopted as a way of directing large streams of organic waste away from landfill with windrow composting and tunnel composters, playing a key role. However falling compost prices and the inability of these technologies to deal with a large fraction of the organic waste stream not suited to composting has led to re-assessment of these technologies. PacPyro has clear advantages over composting including cases where:
- • Landfill avoidance or minimisation is a clear
objective – volume reduction of the waste material can be very valuable as a
waste management tool;
- • Organic wastes have woody factions, high
nitrogen content or plastics contamination;
- • Energy recovery can be used to enhance the economics of the waste management;
- • Municipal
and in some cases corporate carbon liabilities
can be offset via improved organics
management and the production of renewable
energy and biochar; and
- • Organic waste streams are often long distances
from compost markets. Biochar conversion significantly reduces the
volume of product, while concentrating nutrients and eliminating moisture. This decreases the cost of transport to agricultural
and horticultural markets.
In many circumstances, PacPyro’s technology can complement an existing composting facility as the combination of the two provides the following benefits:
- • Increases the amount of waste diverted from landfill as PacPyro’s technology can manage oversized and contaminated materials; and
- • Electrical energy generated by PacPyro can be used to produce the power required for the composting facility.
Pacpyro offers an alternative to traditional approaches to managing ‘wet waste’ including industrial sludges and biosolids which incur high management costs relating to bulky transport, land filling charges and land application to otherwise productive land.
The ability to process wet feedstocks (up to 85% moisture), onsite (due to a small footprint) combined with a capability to value add or reduce the volume of waste streams offers a compelling option. Again the technology works well in combination with digester technology by using the output of the digester as a feedstock which can be processed into energy and/or biochar.
