Case Study


The company

Renshaw is a British food manufacturing company with 120 years’ experience in cake decorating expertise, product innovation and inspiration.

The company prides itself on having a predominantly local workforce and being the grantee of a Royal Warrant from Her Majesty Queen Elizabeth II, having first been granted one by George VI in 1950 for almond products.

Renshaw is the leading British manufacturer of ready-to-roll icing, marzipan, frostings, caramel and mallows. It supplies specialist sugar craft shops, bakeries and general wholesalers, as well as major grocery retailers. It also supplies local distributors in over 30 countries worldwide.

All production comes from the Liverpool site which creates approximately 20,000 tonnes of finished product each year and all sugar used in Renshaw products is milled on site to ensure it meets exacting brand and product standards.

The need

Renshaw’s business operations generate a high volume of waste, mainly cardboard, food and general waste. The company was looking for a waste management partner that could ensure that all their waste was managed in the most effective way, with a zero to landfill target and in line with all current legislation.

There was also a need to:

  • Review how the service yard was being used to collect and store waste
  • Assess the effectiveness of on-site waste management equipment
  • Design and implement a new and bespoke waste management strategy
  • Identify waste streams that could be separated from general waste and recycled Identify potential new sources of income through recyclables
  • Train all waste operatives on site to maximise compliance with the new strategy

The solution

B&M Waste Services installed two new compactors to deal with the high volume of general waste and leftover large cardboard items (which have become a valuable new source of income).

General waste is taken to B&M’s Materials Recovery Facility (MRF) eight miles away on the Wirral where any recyclables are removed before being sent on for processing and 100% recovered as Refuse Derived Fuel (RDF).

B&M provided a number of colour-coded containers to store additional segregated recyclates, such as plastic buckets. The nut skins left over from the processes on site are blown directly into a large covered skip and when full this is taken to a local farm and used for composting.

B&M also held a number of training sessions for employees to help them understand their environmental responsibilities and how and why waste is segregated.

The results

The simplified waste collection, storage and recycling services that B&M provides to Renshaw has allowed its staff to carry on doing what they do best – make top quality baking ingredients, while the improved tidiness and ambience in the service yard area is more appealing to onlookers who come for site visits and audits.

The 2022 environmental report revealed that Renshaw generated over 7000kg of cardboard waste, 14000kg of general waste and 450Kg of organic food waste, none of which was sent to landfill. 100% of cardboard waste was sent for recycling and 100% of food waste was sent to an anaerobic digestion plant where it is used to create electricity. Of the mixed municipal waste collected, further recyclables were extracted and the residual waste was sent to a refuse derived fuel plant where it is used to generate electricity.

To further improve the environmental performance on the site, Renshaw and B&M are looking to introduce an office recycling system. This will involve establishing new recycling stations with clear signage to promote better segregation inside the offices and canteens. Also, plastic shrink wrap from the factory is also being considered for baling which will create a further income source while further reducing general waste tonnages.
