Quality Control Procedures

Quality Control Procedures

Ask any wood pellet boiler manufacturer and they will tell you that having a consistently high quality pellet, is critical in ensuring the optimum performance of their boilers. Consequently, at Woodpellets2u we take product quality extremely seriously.

To make sure we consistently deliver on product quality, Woodpellets2u follows very strict quality control procedures, throughout every stage of the manufacturing and delivery processes.

Manufacturing

1. Only clean timber in the form of saw dust, wood chip or wood in the round is used to make wood pellets
2. The raw material is screened to remove any unwanted material such as bark
3. During the manufacturing process, pellets are tested on a regular basis for:
   1. Density: Greater than 600kg per m3
   2. Moisture Content: Less than 10%
   3. Mechanical Strength: Greater than 97.5%
   4. Dust Levels: Less than 1%
4. Further samples are taken periodically and sent for testing at an accredited ENPlus laboratory for:
   1. Ash Content: Less than 0.7%
   2. Ash Melting Behaviour: At least 1200C
   3. Calorific Value: At least 4800kWh per tonne
   4. Presence of trace metals: Less than specified weight of Arsenic, Cadmium, Chromium, Lead, Mercury, Nickel, Copper, Zinc
5. Pellets that do not meet the quality standards are removed and segregated. (N.B. These pellets do not go to waste as they have alternative uses such as animal bedding).
6. Before being bagged or loaded into delivery tankers, pellets are filtered to remove any further dust that may have built up during storage

Loose Delivery

1. Loose deliveries are made using only our own state of the art delivery tankers, operated by fully trained and experienced drivers. These vehicles come equipped with sophisticated control valve systems and a vacuum pump to ensure that pellets are delivered intact and with a minimum of dust.
2. On arrival at the delivery site, a check list is completed to ensure that the storage is suitable to accept the pellets and that delivery can be made in a safe manner.
3. A sample of pellets is taken at time of delivery, which will be kept for a specified period and is available for testing should a problem arise with the quality of the pellet after delivery. In this way Woodpellets2u is fulfilling the requirement of boiler manufacturers, installers and users to supply pellets that comply with the ENPlus A1 quality standard every time.

Bagged Delivery

1. Bagged product is to be sent to CPL’s National Distribution Centre (NDC) for onward dispatch to the customer.
2. A bag from every delivery into the NDC will be taken, labeled and stored for 9 months so that it is available for testing should a problem arise with the quality of the pellets after delivery
