Planning and Design
CRS has its own in-house Engineering and Design team. The experienced project and CAD engineers custom design every plant to meet each clients individual requirements.
By listening to the client's wishes and constraints with regard to feedstock, capacity, site availability, proposed product end use, the design team ensures that the plant size, pre-treatment regime, composting process and final maturation and screening are tailored to achieve the client's objectives. Every plant is unique.
As the plant designers, CRS play a significant role in the process of seeking the appropriate permits including preparation of planning applications, site working plans, environmental statements, and HACCP documentation. This can be undertaken in collaboration with the clients usual consultants where required, or CRS can take responsibility for the whole permit application process.
Site assessment
CRS will visit proposed locations for composting facilities with clients and / or clients consultants to advise on and discuss the suitability of the site with regards to layout and position. This is usually done prior to the designing of the plant to ensure the optimum design with respect to local conditions, e.g. drainage and slopes, neighbours, and the potential for expansion.
Feed specifications
In order to design a facility it is critical that the best available information is used. Feedstock tonnages, composition, seasonality changes and potential growth are all issues that must be appraised at this stage. CRS bring to this assessment process experience of both MBT and Kerbside collected material.
Drawing
The CRS design team use the full range of modern CAD capability. The design engineers produce scale layout drawings and elevations as well as 3D visualisations and models.
Service requirements
Basic elements of plant design are the drainage layouts and the utility requirements including water, sewerage and electricity. By specifying all aspects of the civils and process technology the service requirements of the plant are included from the start of the design process. CRS will also calculate the power loading of all equipment to ensure an adequate power supply.
Automation
For large scale plants the CRS team design and build labour-saving automation. For example; an automated extending conveyor loading system for the composting tunnels.
Specifications
CRS will take the clients requirements and from these develop full procurement specifications for all the plant including building, civils, fixed and mobile plant.
Costings
CRS calculate both Capital and Operating costs when required. This information can be indicative only or be developed through to fixed quotations when appropriate.
| Examples of CRS Design Criteria |
| Flexible and modular The CRS designed IVC system is modular to make it easy to increase plant capacity as waste collection systems develop. Additional tunnels can be added without the need to build a further reception building. The maturation area can be increased to allow for longer maturation and the production of a higher quality product. Given the fluidity of the waste treatment market, flexibility and adaptability are seen as important design criteria by CRS. |
| ABPR The ABPR legislate to minimise the possibility of contamination of processed waste by pathogens e.g. salmonella. The design concepts required to meet the letter and spirit of ABPR are built into the plans for a CRS plant from the outset. For example an important part of the preventative measures is the reduction of the potential for back contamination of processed or clean waste by fresh waste. All CRS IVC facilities are designed to minimise this potential. Design features include: all drainage runs from the clean area of plant back to the reception area; composting tunnels with doors at both ends to facilitate one-way flow of materials; two banks of tunnels, one for 1st barrier and a discrete second bank for 2nd barrier composting; enclosed walkway between barrier 1 and 2 tunnels to minimise run off water. |
Services
| Permit Documentation |
| Planning applications Many documents and documentary evidence are required for planning applications. CRS are able to assist with the information essential for a successful planning application including scale drawings and elevations, plant specifications and process descriptions. |
| HACCP All ABPR compliant composting facilities require a HACCP (Hazards and Critical Control Points) plan. This plan identifies all areas of the plants operation that could be a potential hazard under the ABPR. CRS have experience of producing such documents to the satisfaction of the SVS. |
| Site working plan CRS can produce the site working plan as needed for the EA licence. |
