WHAT IS COMPOST?

Compost is the result of the organicbreakdown of green and food waste, undercontrolled and monitored conditions.Compost is an important product to thelandscaping industry and can providevarious benefits in projects involvingreclamation, restoration and theimprovement of land. Compost is a sourceof organic matter and can improve thephysical and chemical properties of the soilto which it is applied, enhance plantgrowth, stimulate biological activity andimprove resistance to erosion.BSI PAS 100 compost is ideal because notonly is it a rich source of nutrients, it is alsoquality assured and therefore reliable andconsistent. WRAP has identified a numberof producers of BSI PAS 100 compostspread across the UK.

CONTROL MEASURES

BSI PAS 100 includes controls such as theHazard Analysis and Critical Control Point(HACCP) measures, to ensure that risks ofadverse impacts to the environment andhuman health are minimised.The BSI PAS100 composting processeliminates most plant and humanpathogens that may be present in thefeedstock, and quality and regulatorymeasures are in place to ensure that it is asafe and reliable material to use.Compliance with BSI PAS 100 providesstrict control over chemical and physicalcontaminants likely to be present incompost, for example arsenic, cadmium,copper, lead, mercury, nickel, selenium, zinc, glass and plastic.

QUALITY COMPOST ACROSS THE UKBSI PAS 100 sets the criteria for theproduction of quality compost that can beused in land reclamation and provides theassurance required to users.

In Scotland, compost produced incompliance with BSI PAS 100 is consideredas fully recovered and therefore is nolonger regarded as a waste material,provided that a secure market for thismaterial exists.

In England, Wales and Northern Irelandcompost must also comply with therelevant Quality Protocol to be fullyrecovered and not considered as waste.

The Compost specifications for thelandscape industry recommend thatadditional requirements to the BSI PAS 100criteria should be met for different enduses in order to ensure that the product isfit-for purpose. These are summarised inthe accompanying Technical Documents.The Compost specifications for thelandscape industry are currently underreview and a new version will be publishedShortly.

Application of compost to reduce erosion on an engineered slope, Nafferton Farm, NorthumberlandThe project examines the effectiveness ofcompost to stabilise the surface andsubsurface of an engineered slope in orderto both prevent erosion and enhancevegetation establishment.

Centenary Riverside

An innovative approach was used tostabilise this clay bank and protect it fromerosion. Compost was used for bankstabilisation and soil creation. The compostsoil was sown with a fast growing seed mixto provide vegetation cover to protect thecompost from erosion. Compost socks havebeen installed along the riverbank toprotect it from scouring. The compost hassignificantly reduced erosion and hasprovided the growing medium in whichplants are thriving.
