If you missed the Lafarge public presentation at the clubhouse on the 12th of July 2016 you may want to read the following.

Lafarge Regulatory Permit.

Lafarge has a temporary regulatory permit from the Ministry of Environment and Climate Change to study materials from industrial, commercial and institutional (ICI) sources as well as construction and demolition sources. The permit covers the following materials.

  • A... Pre-consumer/post-diversion materials (coffee roasting chaff; materials made predominantly from biomass; manufacturing end rolls and cores; carpet cuttings; textiles; paper fibre/wood/plastic composite materials; sawdust; woodchips)
  • B… Construction and demolition materials (materials made predominantly from biomass; rugs; floor laminates; wood treated with organics; non-recyclable packaging)
  • C…  Post-consumer/post-diversion materials (cardboard; banknotes; disposable beverage cups and lids; non-recyclable paper fibre packaging and related similar products; printed paper; paper towels; materials made predominantly from biomass; textiles)
  • D… Treated wood (railway ties; telephone poles)
  • E… Asphalt shingles.

Project One of their Low Carbon Fuel (LCF) experiment has been completed. It was a success in terms of emissions and performance. They were burning construction waste, treated wood and asphalt shingles.

The pre-burn preparation storage, sorting, shredding and grinding were carried out at remote facilities and the processed LCF trucked into Bath.

Following the successful air testing program in October 2014, Lafarge undertook an Environmental Screening Process to evaluate the impacts and benefits of using C&D materials, treated wood, and asphalt shingles at the Lafarge Bath Plant.  This included conducting studies on air, noise, surface and ground water, traffic, and socio-economics. This environmental assessment was successfully completed in April 2016.

  • Lafarge is now in the process of submitting regulatory permit applications to the Ministry to allow the permanent use of these fuels at the Bath Plant.

Project Two (Evaluation of Low Carbon Fuels – Project 2, Considerations for Permanent Use. Click Here for details) is about to commence. There is little reason to believe it will not be a success in terms of emissions and performance. Fuel size, mixture ratios and a host of other parameters now have a baseline. The lessons learned from Project One will smooth the way for a successful experiment.

Preliminary air emission testing (Project Two)

Preliminary air emission testing was started in November 2015 on the following fuels

  • Paper fibre/wood/plastic composite materials, such as manufacturing rejects and trimmings of un-used off-spec personal hygiene products, household     goods, packaging labels and tape
  • Non-recyclable paper fibre packaging (and related similar products), such as rejects and trimmings from paper recycling facilities (i.e. ragger tails)
  • Textiles, carpet cuttings, manufacturing end rolls and cores
  • Disposable beverage cups and lids (e.g. K-cups).

Preliminary results from the air testing program on LCFs in November 2015 are demonstrating similar positive results; complete results will be available in the fall of 2016.

Consequently, Lafarge is in the early stages of a second Environmental Screening Process (i.e. Project “2”) to evaluate the impacts and benefits of using the following fuels at the Lafarge Bath Plant

  • Paper fiber wood/plastic composite materials, such as manufacturing rejects and trimmings of un-used off-spec personal hygiene products, household goods, packaging labels and tape
  • Non-recyclable paper fiber packaging (and related similar products), such as rejects and trimmings from paper recycling facilities (i.e. ragger tails)

Future Project Three

Lafarge is now proposing to amend their regulatory permit to extend the testing period by one year and to add the following fuels to the list of approved fuels for study.

  • Non-recyclable rubber (not including used tires) and rubber recycling by-products (e.g. polyester/nylon fiber from tire recycling facilities);
  • Non-recyclable plastics from Material Recovery Facilities and the ICI sector
  • Non-odorous oversized and/or unused compost materials (e.g. twigs, plastic bags).

Should the permit amendment be approved by the Ministry, Lafarge will complete air emission testing on these at some time in the future.

Lessons Learned. (A very significant change is coming)
One of the lessons learned from Project One was that securing a consistent, quality supply of processed LCF material is a critical path issue. The outside suppliers were not producing the required quality or a consistent supply to the Bath facility. To combat this Lafarge will take control of the supply chain. Project Two will see Lafarge installing bulk storage facilities as well as sorting, shredding, grinding and bulk material handling equipment on the Bath site.

In Project Two they will add a significant variety of additional materials to the construction waste, railway ties and asphalt shingles used in Project One. Paper fibre/wood/plastic composite materials, such as manufacturing rejects and trimmings of un-used off-spec personal hygiene products, household goods, packaging labels and tape; non-recyclable paper fibre packaging (and related similar products), such as rejects and trimmings from paper recycling facilities (i.e. ragger tails); textiles, carpet cuttings, manufacturing end rolls and cores; and disposable beverage cups and lids (e.g. K-cups).

Lafarge are planning to burn 91,250 Tons of processed LCF material a year and will process the majority of this material at the Bath facility. They are going to store almost 20,000 tons of processed LCF material on site. (Includes unprocessed material). In addition to the needs of the Bath facility (250 tons a day) they will be processing as much as 125 tons a day of additional material for shipment to other sites.

Although Lafarge are considering only non‐odorous materials for use in the facility such items a paper cups, plastic lids, plastic bags etc. from “Material Recovery Facilities” (Garbage dumps?) could potentially contain residual odorous bio materials.

Project  Two is unlikely to be a failure in terms of emissions and performance. What it will see is a considerable investment by Lafarge to install processing equipment, sorters, shredders, grinders, runoff ponds and large scale storage and handling facilities.

Project two will see 10 Hectares (LCF 5) to the east of the facility dedicated to storing unprocessed material. A large enclosed storage building (LCF 4) to the north west of the main plant and a large storage area for unprocessed material adjacent that. (FF 1). The staging/processing building (LCF 1) will be to the north east of the plant and will include a runoff collection pond.

Processing 130,000 tons of LCF a year is not a small operation, it could easily bring noise, dust, additional traffic, odours and the potential for ground water contamination into our back yard.

Lafarge are aware of this and are taking remedial actions. They are building indoor storage for processed LCF, a runoff pond and are proposing to store excess processed LCFs under tarpaulins. Once completed the results of Project Two will be presented at a public meeting followed by applications for permanent use.

The processing equipment, which has the potential to create noise and dust, will be shielded to keep both within acceptable limits.
