   Permitting / Environmental Compliance 


Composting is an environmentally beneficial activity and good business! Several regulatory permits and issues must be handled in order to operate legally.  The Washington Solid Waste Handling Standards (WAC 173-350) that went into effect February 10, 2003, apply directly to composting facilities. Under these regulations, operating and permitting requirements vary depending upon the feedstock type and quantity of material you will be processing.  Benefits of operating under a permit include the ability to meet WSDOT specifications for erosion control media, and the potential for listing in WSDA's Brand Name Material List as an approved Organic food production amendment.   

Terre-Source has years of experience with solid waste handling permit applications and air agency permit applications for many types of operations.  Our expertise includes applying the regulatory requirements, streamlining the permitting process, and working with the various governmental agencies required to get your facility permitted as quickly and efficiently as possible.  We will work with you to establish positive relations between you and your regulators and help you get off to a great start creating  high-quality beneficial products.    



   Facility Design


The microbial composting process can be optimized by taking into consideration the needs of the microbes, encouraging their growth, and utilizing their metabolic by-products, heat and plant soluble nutrients, to create a high quality, marketable product. 

Terre-Source can help you develop a facility design that optimizes your site and feedstocks to while minimizing your material handling costs.  A good-fit design can help your operator efficiently monitor the microbial activity, meet regulatory requirements, and produce a superior product.


   Environmental Education


          "Full Circle" Composting in schools provides a hands-on experience for students to learn and to apply lessons in ecology, biology, microbiology, botany, chemistry, soil science, nutrition, food production, weights & measures, Scientific Method and more!  Such a program helps schools reduce the wastes generated and increase the sustainability of the facility. It reduces the carbon footprint of the school, and provides opportunity for community interaction.

Terre-Source can:

  • help your school perform a 'waste audit' to determine the amount and type of food waste that will be composted,

  • select an appropriate composting system,

  • integrate food waste collection and diversion into your school's activities,

  • help your school during 'start-up' of collection as well as setting up your composting system, 

  • provide on-going trouble shooting for your composting program and your teachers, students, and operators,

  • present the benefits of 'Full-Circle' composting programs and help teachers with technical questions about composting and all of the subjects that students can learn from composting. 

A well-fit system and appropriate planning can help your program Start Up for Success!  The fun your students can have brainstorming fund raising or waste reduction activities while they learn to ease the waste stress on our planet cannot be underestimated!


   Process Consultation


Terre-Source helps composters produce high quality compost products by providing expertise in the composting process.  We can help you meet your client's specifications and increase your market!

 Terre-Source provides:

  Process recommendations to help control the composting parameters to help ensure good pathogen reduction, odor control, weed seed kill, and regulatory compliance that will create a high quality product focused on your market;  

Careful scrutiny of monitoring data such as temperature, oxygen content, and laboratory test results as well as site inspections to help maintain optimum composting efficiency;

Third Party Review of compost facilities to help streamline record keeping, annual reporting, and product handling;

Terre-Source can also prepare the required annual reporting and help pull together the information needed from the process monitoring and material volume data collected during the year.


   Organic Listing


          Compost is becoming recognized as an important source of organic matter and slow-release nutrients for organic and conventional agriculture.  Organic farmers have the added burden of needing to report all inputs to show that they meet the National Organic Program's requirements for Organic Food Production.  The Washington State Department of Agriculture maintains a "Brand Name Materials List" of products that meet those requirements.  Having your compost product listed on that approved list can increase your market for finished compost and establish your product in the new and growing arena of organic agriculture!

Terre-Source can prepare your application, help you with your sampling and analyses, and with your marketing materials so that your organic soil amendment product is at the fingertips of organic farmers in Washington State.


 Recycling Outreach / Coordination / Education  
           "Reduce - Re-Use - Recycle" is becoming even more important as society realizes the impact of continuous extraction of resources to produce the items we use daily.  From reducing our carbon footprint to energy costs of production and ecological costs of producing raw materials, society needs to use materials more wisely.  Terre-Source can help companies and governments implement recycling programs for landscaping wastes, food wastes, and other organic materials, as well as all of the more traditional recyclable materials.  We can also help investigate uses and re-uses for other waste products to create innovative and cost effective recycling programs. 

Terre-Source can help you reduce your disposal costs, your impact on the earth, and simultaneously increase your environmental image. 


   Personnel Training  


Composting uses biological processes to heat and degrade organic feedstocks to produce a biologically stable, humus-rich, beneficial soil amendment.  Optimizing composting microbial processes is similar to raising crops and larger animals.  A farmer must provide for his or her animals' needs such as food, water, and environment for them to thrive and reproduce.  The compost facility operator is essentially a 'microbe farmer' who must provide those elements for his or her biota.

Because any biologic system is necessarily complex, the operator must pay constant attention to the behavior of the system. Ultimately it is the Operator who most influences the success of the process.  The skill and expertise of the Operator is, therefore, critical to the success and ultimate production of high quality compost.

Terre-Source can provide Operator training and on-going consultation on all aspects of the composting process and compost facility set up.
