Reuse of wastewater for crop irrigation is essential to sustain agricultural growth in a country such as Morocco where water resources are scarce due to the hot, arid climate. However few towns in Morocco have sewage treatment facilities and reuse with untreated wastewater is therefore widespread, and the public health risks from excreta related disease high. A suitable treatment system to provide safe water for irrigation is the use of waste stabilisation ponds, which provide an effluent high in microbiological quality and also high in fertilizer value due to the large amounts of algae which are normally discharged. It was therefore decided to implement an integrated waste stabilisation pond, effluent reuse system as a demonstration scheme of the advantages, both in terms of improved crop productivity and public health of the local community. The town of Boujad in Kouribga Province was selected as a suitable site and this paper describes the background to the development.

The City

In the City of Gloucester, Massachusetts, 30% of the Soft-shell Clam (Mya arenaria) beds in a tidal inlet known as the Annisquam River are not harvestable owing to the discharges of untreated sewage from the surrounding area. A large proportion of the total area of the clam-flats has been closed to clamming because of exceedingly high levels of coliform Bacteria in the clams and in the water. These polluted areas represent a ‘loss’ of resources for the community, and they were surveyed in 1980 to determine the number and value of Clams which could have been harvested if only the sewage discharges had been controlled.In the productive areas of the closed-to-fishing flats, which totaled 25.9 ha, the densities of Clams larger than 2.5 mm were found to be statistically the same on the 9 flats sampled and averaged 122.3 per m2. The average number of legally harvestable Clams (those with shells more than 51 mm in length) was 23.3 per m2, and the total yield that could have been harvested in 1980 was estimated at 6 × 106 Clams. Assuming that only 50–60% of the Clams would actually have been harvested in a year (i.e. 3.2 × 106 animals), the local community lost $332,400 in retail sales alone for lack of adequate sewage treatment facilities. Locally, 70% of the harvest goes into the restaurant trade where a bushel (35.2 1), which contains some 1,600 animals, retails for $210, and 30% is sold fresh at $64 per bushel.

Pyridine Degradation

Bacterial strains capable of degradation of 0.8-15.8 g/1 pyridine hydrochloride have been isolated from activated sludge of municipal biological treatment plants in Perm (BOS) and local treatment facilities of the LUKOIL-Permnefteorgsintez enterprise (PNOS). The strains were identified as Achromobacter pulmonis and Burkholderia dolosa. The optimal pyridine concentration for the growth of the isolated strains was 4.0 g/1. The pyridine degradation during the A. pulmonis PNOS and B. dolosa BOS cultivation on a medium with ammonium chloride and glucose and without additional nitrogen or carbon sources was studied. It was shown that the strains are able to accumulate biomass in a medium with pyridine as the sole carbon and nitrogen source; the addition of glucose to the medium (1 g/L) accelerated the pyridine degradation by A. pulmonis PNOS, but inhibited the process carried out by B. dolosa BOS. B. dolosa BOS and A. pulmonis PNOS biofilms efficiently utilized pyridine during growth on basalt and carbon fibers; the highest rate of pyridine utilization (1.8 g /(L day)) was observed in A. pulmonis PNOS biofilms on basalt fibers. pyridine, biodegradation, activated sludge, biofilms, Achromobacter pulmonis, Burkholderia dolosa The authors grateful to Dr. I.I. Tchaikovsky, Head of the Laboratory of Geology of Mineral Deposits of the Mining Institute, a branch of the Perm Federal Research Center, for help with electron microscopy of the samples. This work was carried out as part of a state assignment on the topic « Study of the Functional and Species Diversity of Microorganisms Useful for Ecocenoses and Human Practical Activity», registration number R&D AAAA-A19-119112290008-4.

Through the extensive research and deep analysis of existing problems in cleaner production, four middle/high expense plans were set forth, demonstrated and implemented. These four implement plans included high efficient steam traps, energy saving system of steam boiler, improved sewage treatment facilities and vacuum raw material feeder. The total investment was 330 thousand Yuan RMB. The annual discharge of waste water was reduced by about 30 thousand tons and annual economic profit was 680 thousand Yuan RMB. Moreover, better environmental and social benefit was created. More importantly, a sustainable cleaner production mechanism was established for the factory.

Farmers Market

This article inductively develops a model of how farmers market organizations can contribute to reduce food waste, fight poverty, and improve public health through innovative Corporate Social Responsibility (CSR) practices enabled by networked activity systems. To this aim, a ten-year longitudinal case study of one of the biggest Italian farmers markets has been conducted, based on triangulated data from participant observation, interviews, and internal documents collection. This study suggests that farmers market organizations are in the position to leverage their inter-organizational relationships, institutional role, and power to build collaborative networks with businesses, government bodies, and charities, so that concrete CSR-based virtuous circles on surplus food donation are triggered at the organizational field level. Answering the call from United Nation Goals for successful examples on SDG 12, this case presents how several CSR levers can have a social and environmental impact allowing farmers and their market organizations to increase their efficiency and accountability to the local community, improve processes, reduce food waste, and contribute to public health and social inclusion. CSR actions have co-evolved with significant changes in organizational logics and identity, thus enabling accountability to the local community and innovative network-level auditing of the relevant organizational processes.

Background: Vermicomposting is the agricultural technique of conversion of organic wastes to a fertile product, which can result in better crop growth and production. However, even though earthworms are the main organisms participating in the process, the microbes associated with it also have an important role to play. These microbes degrade the waste products biochemically and are responsible of the conversion processes. Few studies are carried out on microbial diversity and related enzymes activities in the vermicompost prepared from different organic waste materials. Methods: In this paper, we isolated both bacteria and fungi from seven different types of vermicompost, using different selective media. We also studied the activity of hydrolytic enzymes that are associated with the isolated microbes.Result: It was observed that bacteria like Bacillus sp., Pseudomonas sp., Klebsiella sp., Staphylococcus aureus, Streptococcus, Micrococcus, Actinomycetes, Pigment producing Actinomycetes, Streptomyces, Azotobactor and fungi like Penicillium purpurogenum, Aspergillus sp., Alternaria alternata, Fusarium solani, Rhizopus sp., Mucor hiemalis, Myrothecium verrucaria etc. were present in our vermicompost preparations. The presence of nitrogen fixing bacteria, phosphate solubilizing microorganisms and PGPR indicated the good fertilizer value of the vermicompost samples. It was also observed that the diversity of microbes present supported significant levels of CMCase Exoglucanase, Xylanase, β-Glucosidase, Phosphatase and Urease activities.
