Composting in the Subarctic – Inputs
Greens and Browns: Composting Input Management Actium Composting equipment allows for environmentally sustainable disposal and reuse of organic materials in the form of compost. The program I work with invested in an Actium Batch Composter Drum, to primarily create local fertilizer for subarctic community gardens located in Fort Albany First Nation, Ontario, Canada. As a secondary benefit, the ...

Composting in the Subarctic – Operations
The Actium compost drums are used in a variety of climates. In the tropical and subtropical climates, the composter is used year-round. In temperate climates, the Actium Batch Compost Drum can be used year-round because the drum is insulated. However, the decaying process can be slowed where winter temperatures are below freezing for a prolonged period. There are two approaches to maintain hot ...

Measurement of Total Carbon in Soil and Compost by TOC Solid Sample Measurement System
Soil contains a large amount of organic matter such as plant residue that can be decomposed by microorganisms. This organic matter plays a key role in plant growth by maintaining good chemical and physical conditions in soil and is useful in improving and stabilizing the productivity of agricultural crops. Compost, a type of fertilizer in which organic matter is decomposed by microorganisms, ...

How to speed up composting
How to Speed up Composting Composting is a natural process. You can say it’s the most important recycling process in the ecosystem. Every living thing on the planet eventually dies and breaks down into soil to help new plant life (and, subsequently, every other living thing) flourish. By learning about the key factors in making fast compost we can begin making our own compost piles more ...

Canadian food inspection agency (CFIA) manitoba composting exercise case study
Overview: Nordevco was invited to participate in a Canadian Food Inspection Agency (CFIA) composting exercise by the CFIA Manitoba Team. The purpose of Nordevco’s participation was to evaluate the impact of BactiDomus Technology on the composting process specifically related to achieving and maintaining temperatures appropriate for the inactivation of the pathogen responsible for avian ...

Slaughterhouse carcass waste composting case study
Slaughterhouse waste was treated with BactiDomus Technology compost accelerator to monitor the effects of the treatment against untreated waste. The goal of the project is to increase the efficiency of the composting process to reduce the total time needed to turn the waste into compost. Two separate bins of waste were treated with BactiDomus Technology compost accelerator, the first on August ...

A comparative study between composting and vermicomposting for recycling food wastes
The main objective of the present work was to evaluate the potential of the epigeic earthworms Eisenia fetida and Eudrilus eugenaie regarding the decomposition of food wastes. The effectiveness of composting and vermicomposting for the treatment of food wastes was judged by analysing a wide range of physic–chemical parameters. The results from the compost process monitoring showed porosity rise ...

Developing value added bioactive timber waste vermicompost with addition of microbial inoculants
A study conducted at Vermiculture Research Station (VRS), Aligarh, to transform the timber solid waste vermicompost (TSWV) into bioactive compost with the addition of beneficial microbes has brought to light feasibility of a potential technique to develop value added quality product with higher agronomic value for the first–time. TSWV was inoculated with microbes Azotobacter chroococcum, Bacillus ...

Microbial characterisation of vermicompost and compost of urban waste processed by three earthworm species - Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus
Species diversity of bacteria, fungi and actinomyctes of vermicompost and compost of the organic fraction of municipal solid waste, vegetable market waste and flower waste were assessed using pour plate technique. Of the total 91 entities, 62 were bacteria and 29 were actinomycetes in MW, followed by that of MSW and FW, with 59 and 55 bacterial; 25 and 22 actinomycetes entities, respectively. The ...

Case Study: Greenview Environmental
Needham Market, Suffolk In terms of tonnage, Greenview is the UK’s largest independent processor of organic material. Established in 1985, the firm now operates from 6 sites around the country and processes over 300,000 tonnes of organic waste each year. The high-quality compost produced goes on to be used for horticultural and agricultural purposes as a soil improver. CompostManager has ...

Kinetic study of compost liquor nitrification
This study is a first kinetic approach about the compost liquor treatment by activated sludge. This industrial wastewater is highly loaded in organic and nitrogen compounds (COD≈12,000 mg L−1 and NH4+-N≈4,000 mg L−1). The possibility of its treatment in an urban WWTP is studied measuring ammonia oxidation rate with non-acclimated sludge to the industrial effluent. Compost liquor appears as an ...

Sludge composting, sludge pretreatment and radiation technology: a review
The paper reviews the state-of-the-art technologies on sludge conditioning and stabilisation. Radiation technology, best contextualised within the concept of Green Chemistry, is yet another developing area of sludge pretreatment. Besides revisiting some important aspects of sludge treatment by composting, this review paper also appraises the application of gamma ray and ultrasound irradiations ...

Leaf composting in cold climates: a theoretical and an experimental evaluation
There are many factors influencing the process of composting organic waste. This paper provides an experimental and theoretical evaluation of the leaf composting process to elucidate the importance of these various factors during composting of leaves. The analysis is performed specifically for the environmental conditions encountered in cold climates. Theoretical models are developed to evaluate ...

Home Composting Diversion: Household Level Analysis
The goals of the present study were to (i) verify Parfitt’s (2005) household-level models of home composting diversion, (ii) provide additional insight into how those diversion factors were derived, (iii) extend the modelling approach to consider garden waste in residual and garden waste collections, and (iv) track the performance of compost bins supplied by WRAP (Waste & Resources Action ...

Pilot project cuts odor, cost for humanure compost
Utah Valley Daily Herald Article on the benifits on using micro-pore membrane compost covers when composting highly odorus material. In February of 2009 Utah Valley's North Sewer Distirict conducted a pilot study to determine the effectivness of mirco-pore membrane compost covers in reducing odors from biosolids (sewage sludge) composting. Odor testing was conducted over a term of one month ...

Disposal of seaweed wakame (Undaria pinnatifida) in composting process by marine bacterium Halomonas sp. AW4
A novel marine bacterium, identified as Halomonas sp. AW4 by partial 16S rDNA analysis, was isolated from the seaweeds in Awaji Island, Japan. Strain AW4 grew well even in the wide NaCl concentration ranges of 0?3 mol/L, where it showed an optimal growth in the presence of 0.5 mol/L NaCl. The organic components were reduced to 73.6% of initial dry weight after 168 h of composting by inoculation ...

Modeling composting kinetics: A review of approaches
Composting kinetics modeling is necessary to design and operate composting facilities that comply with strict market demands and tight environmental legislation. Current composting kinetics modeling can be characterized as inductive, i.e. the data are the starting point of the modeling process and determine the type of model used. It is argued that the inductive empirical approach has been ...

A statistical approach to evaluate compost genotoxicity
Parallel experiments were carried out to evaluate the induction of genotoxic effects in Vicia faba seedlings treated both with aqueous and organic extracts (dimethyl sulphoxide 5%) of 13 composts, or grown on soil samples to which different doses of the same composts were added. Pearsons linear correlation coefficient and multiple regression were used to study how these two different ...
